Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974720, here are decompositions:
- 67 + 4294974653 = 4294974720
- 73 + 4294974647 = 4294974720
- 79 + 4294974641 = 4294974720
- 137 + 4294974583 = 4294974720
- 139 + 4294974581 = 4294974720
- 151 + 4294974569 = 4294974720
- 193 + 4294974527 = 4294974720
- 227 + 4294974493 = 4294974720
Showing the first eight; more decompositions exist.
