Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489376, here are decompositions:
- 13 + 31489363 = 31489376
- 97 + 31489279 = 31489376
- 199 + 31489177 = 31489376
- 229 + 31489147 = 31489376
- 307 + 31489069 = 31489376
- 313 + 31489063 = 31489376
- 349 + 31489027 = 31489376
- 367 + 31489009 = 31489376
Showing the first eight; more decompositions exist.
