Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598748, here are decompositions:
- 31 + 31598717 = 31598748
- 47 + 31598701 = 31598748
- 61 + 31598687 = 31598748
- 79 + 31598669 = 31598748
- 101 + 31598647 = 31598748
- 157 + 31598591 = 31598748
- 211 + 31598537 = 31598748
- 227 + 31598521 = 31598748
Showing the first eight; more decompositions exist.
