Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47812, here are decompositions:
- 3 + 47809 = 47812
- 5 + 47807 = 47812
- 71 + 47741 = 47812
- 101 + 47711 = 47812
- 113 + 47699 = 47812
- 131 + 47681 = 47812
- 173 + 47639 = 47812
- 269 + 47543 = 47812
Showing the first eight; more decompositions exist.
