Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64980, here are decompositions:
- 11 + 64969 = 64980
- 29 + 64951 = 64980
- 43 + 64937 = 64980
- 53 + 64927 = 64980
- 59 + 64921 = 64980
- 61 + 64919 = 64980
- 79 + 64901 = 64980
- 89 + 64891 = 64980
Showing the first eight; more decompositions exist.
