Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143246, here are decompositions:
- 3 + 143243 = 143246
- 7 + 143239 = 143246
- 109 + 143137 = 143246
- 139 + 143107 = 143246
- 193 + 143053 = 143246
- 277 + 142969 = 143246
- 283 + 142963 = 143246
- 307 + 142939 = 143246
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 143,246 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 143246 first appears in π at position 223,060 of the decimal expansion (the 223,060ordinal-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.
