Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624560, here are decompositions:
- 13 + 31624547 = 31624560
- 53 + 31624507 = 31624560
- 83 + 31624477 = 31624560
- 103 + 31624457 = 31624560
- 131 + 31624429 = 31624560
- 137 + 31624423 = 31624560
- 173 + 31624387 = 31624560
- 193 + 31624367 = 31624560
Showing the first eight; more decompositions exist.
