Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588750, here are decompositions:
- 41 + 31588709 = 31588750
- 71 + 31588679 = 31588750
- 107 + 31588643 = 31588750
- 227 + 31588523 = 31588750
- 257 + 31588493 = 31588750
- 311 + 31588439 = 31588750
- 383 + 31588367 = 31588750
- 419 + 31588331 = 31588750
Showing the first eight; more decompositions exist.
