Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65018, here are decompositions:
- 7 + 65011 = 65018
- 67 + 64951 = 65018
- 97 + 64921 = 65018
- 127 + 64891 = 65018
- 139 + 64879 = 65018
- 271 + 64747 = 65018
- 397 + 64621 = 65018
- 409 + 64609 = 65018
Showing the first eight; more decompositions exist.
