Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158000, here are decompositions:

67 + 157933 = 158000
103 + 157897 = 158000
163 + 157837 = 158000
229 + 157771 = 158000
331 + 157669 = 158000
373 + 157627 = 158000
421 + 157579 = 158000
439 + 157561 = 158000

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 158,000 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 158000 first appears in π at position 750,085 of the decimal expansion (the 750,085ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
