Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142622, here are decompositions:
- 3 + 142619 = 142622
- 13 + 142609 = 142622
- 31 + 142591 = 142622
- 79 + 142543 = 142622
- 241 + 142381 = 142622
- 433 + 142189 = 142622
- 439 + 142183 = 142622
- 463 + 142159 = 142622
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 142,622 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 142622 first appears in π at position 470,877 of the decimal expansion (the 470,877ordinal-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.
