Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51804, here are decompositions:
- 7 + 51797 = 51804
- 17 + 51787 = 51804
- 37 + 51767 = 51804
- 83 + 51721 = 51804
- 113 + 51691 = 51804
- 131 + 51673 = 51804
- 157 + 51647 = 51804
- 167 + 51637 = 51804
Showing the first eight; more decompositions exist.
