Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455032, here are decompositions:
- 61 + 31454971 = 31455032
- 79 + 31454953 = 31455032
- 109 + 31454923 = 31455032
- 151 + 31454881 = 31455032
- 223 + 31454809 = 31455032
- 331 + 31454701 = 31455032
- 379 + 31454653 = 31455032
- 571 + 31454461 = 31455032
Showing the first eight; more decompositions exist.
