Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64560, here are decompositions:
- 7 + 64553 = 64560
- 47 + 64513 = 64560
- 61 + 64499 = 64560
- 71 + 64489 = 64560
- 107 + 64453 = 64560
- 109 + 64451 = 64560
- 127 + 64433 = 64560
- 157 + 64403 = 64560
Showing the first eight; more decompositions exist.
