Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542338, here are decompositions:
- 109 + 31542229 = 31542338
- 271 + 31542067 = 31542338
- 307 + 31542031 = 31542338
- 337 + 31542001 = 31542338
- 349 + 31541989 = 31542338
- 367 + 31541971 = 31542338
- 439 + 31541899 = 31542338
- 577 + 31541761 = 31542338
Showing the first eight; more decompositions exist.
