Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142946, here are decompositions:
- 7 + 142939 = 142946
- 43 + 142903 = 142946
- 73 + 142873 = 142946
- 79 + 142867 = 142946
- 109 + 142837 = 142946
- 157 + 142789 = 142946
- 337 + 142609 = 142946
- 373 + 142573 = 142946
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 142,946 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 142946 first appears in π at position 147,248 of the decimal expansion (the 147,248ordinal-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.
