Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142430, here are decompositions:
- 3 + 142427 = 142430
- 61 + 142369 = 142430
- 73 + 142357 = 142430
- 103 + 142327 = 142430
- 193 + 142237 = 142430
- 199 + 142231 = 142430
- 241 + 142189 = 142430
- 271 + 142159 = 142430
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 142,430 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 142430 first appears in π at position 422,295 of the decimal expansion (the 422,295ordinal-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.
