Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624590, here are decompositions:
- 31 + 31624559 = 31624590
- 43 + 31624547 = 31624590
- 79 + 31624511 = 31624590
- 83 + 31624507 = 31624590
- 113 + 31624477 = 31624590
- 167 + 31624423 = 31624590
- 223 + 31624367 = 31624590
- 227 + 31624363 = 31624590
Showing the first eight; more decompositions exist.
