Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142078, here are decompositions:
- 11 + 142067 = 142078
- 17 + 142061 = 142078
- 29 + 142049 = 142078
- 47 + 142031 = 142078
- 59 + 142019 = 142078
- 71 + 142007 = 142078
- 107 + 141971 = 142078
- 137 + 141941 = 142078
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 142,078 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 142078 first appears in π at position 394,743 of the decimal expansion (the 394,743ordinal-suffix:rd 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.
