Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147812, here are decompositions:
- 13 + 147799 = 147812
- 19 + 147793 = 147812
- 43 + 147769 = 147812
- 73 + 147739 = 147812
- 103 + 147709 = 147812
- 109 + 147703 = 147812
- 139 + 147673 = 147812
- 151 + 147661 = 147812
Showing the first eight; more decompositions exist.
