Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73812, here are decompositions:
- 29 + 73783 = 73812
- 41 + 73771 = 73812
- 61 + 73751 = 73812
- 103 + 73709 = 73812
- 113 + 73699 = 73812
- 131 + 73681 = 73812
- 139 + 73673 = 73812
- 199 + 73613 = 73812
Showing the first eight; more decompositions exist.
