Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615318, here are decompositions:
- 5 + 31615313 = 31615318
- 89 + 31615229 = 31615318
- 101 + 31615217 = 31615318
- 107 + 31615211 = 31615318
- 131 + 31615187 = 31615318
- 149 + 31615169 = 31615318
- 191 + 31615127 = 31615318
- 257 + 31615061 = 31615318
Showing the first eight; more decompositions exist.
