Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517090, here are decompositions:
- 79 + 31517011 = 31517090
- 97 + 31516993 = 31517090
- 109 + 31516981 = 31517090
- 139 + 31516951 = 31517090
- 211 + 31516879 = 31517090
- 271 + 31516819 = 31517090
- 313 + 31516777 = 31517090
- 337 + 31516753 = 31517090
Showing the first eight; more decompositions exist.
