Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535784, here are decompositions:
- 31 + 31535753 = 31535784
- 37 + 31535747 = 31535784
- 43 + 31535741 = 31535784
- 67 + 31535717 = 31535784
- 103 + 31535681 = 31535784
- 113 + 31535671 = 31535784
- 127 + 31535657 = 31535784
- 151 + 31535633 = 31535784
Showing the first eight; more decompositions exist.
