Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142256, here are decompositions:
- 19 + 142237 = 142256
- 67 + 142189 = 142256
- 73 + 142183 = 142256
- 97 + 142159 = 142256
- 157 + 142099 = 142256
- 199 + 142057 = 142256
- 349 + 141907 = 142256
- 463 + 141793 = 142256
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 142,256 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 142256 first appears in π at position 46,279 of the decimal expansion (the 46,279ordinal-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.
