Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142412, here are decompositions:
- 31 + 142381 = 142412
- 43 + 142369 = 142412
- 181 + 142231 = 142412
- 223 + 142189 = 142412
- 229 + 142183 = 142412
- 313 + 142099 = 142412
- 373 + 142039 = 142412
- 421 + 141991 = 142412
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 142,412 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 142412 first appears in π at position 167,264 of the decimal expansion (the 167,264ordinal-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.
