Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598784, here are decompositions:
- 5 + 31598779 = 31598784
- 13 + 31598771 = 31598784
- 31 + 31598753 = 31598784
- 67 + 31598717 = 31598784
- 83 + 31598701 = 31598784
- 97 + 31598687 = 31598784
- 101 + 31598683 = 31598784
- 137 + 31598647 = 31598784
Showing the first eight; more decompositions exist.
