Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517210, here are decompositions:
- 3 + 31517207 = 31517210
- 13 + 31517197 = 31517210
- 61 + 31517149 = 31517210
- 199 + 31517011 = 31517210
- 229 + 31516981 = 31517210
- 331 + 31516879 = 31517210
- 421 + 31516789 = 31517210
- 433 + 31516777 = 31517210
Showing the first eight; more decompositions exist.
