Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 52812, here are decompositions:
- 5 + 52807 = 52812
- 29 + 52783 = 52812
- 43 + 52769 = 52812
- 79 + 52733 = 52812
- 101 + 52711 = 52812
- 103 + 52709 = 52812
- 139 + 52673 = 52812
- 173 + 52639 = 52812
Showing the first eight; more decompositions exist.
