Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530000, here are decompositions:

13 + 529987 = 530000
19 + 529981 = 530000
43 + 529957 = 530000
61 + 529939 = 530000
67 + 529933 = 530000
73 + 529927 = 530000
181 + 529819 = 530000
193 + 529807 = 530000

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 530,000 and was likely granted around 1894.

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

Position in π

The digit sequence 530000 first appears in π at position 407,464 of the decimal expansion (the 407,464ordinal-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.
