Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142258, here are decompositions:
- 41 + 142217 = 142258
- 47 + 142211 = 142258
- 89 + 142169 = 142258
- 101 + 142157 = 142258
- 107 + 142151 = 142258
- 191 + 142067 = 142258
- 197 + 142061 = 142258
- 227 + 142031 = 142258
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 142,258 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 142258 first appears in π at position 355,918 of the decimal expansion (the 355,918ordinal-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.
