Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142000, here are decompositions:
- 29 + 141971 = 142000
- 41 + 141959 = 142000
- 59 + 141941 = 142000
- 83 + 141917 = 142000
- 137 + 141863 = 142000
- 149 + 141851 = 142000
- 167 + 141833 = 142000
- 197 + 141803 = 142000
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 142,000 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 142000 first appears in π at position 837,118 of the decimal expansion (the 837,118ordinal-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.
