Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427422, here are decompositions:
- 193 + 2147427229 = 2147427422
- 271 + 2147427151 = 2147427422
- 331 + 2147427091 = 2147427422
- 379 + 2147427043 = 2147427422
- 421 + 2147427001 = 2147427422
- 433 + 2147426989 = 2147427422
- 601 + 2147426821 = 2147427422
- 1021 + 2147426401 = 2147427422
Showing the first eight; more decompositions exist.
