Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615270, here are decompositions:
- 41 + 31615229 = 31615270
- 53 + 31615217 = 31615270
- 59 + 31615211 = 31615270
- 83 + 31615187 = 31615270
- 101 + 31615169 = 31615270
- 107 + 31615163 = 31615270
- 173 + 31615097 = 31615270
- 257 + 31615013 = 31615270
Showing the first eight; more decompositions exist.
