Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68520, here are decompositions:
- 13 + 68507 = 68520
- 19 + 68501 = 68520
- 29 + 68491 = 68520
- 31 + 68489 = 68520
- 37 + 68483 = 68520
- 43 + 68477 = 68520
- 47 + 68473 = 68520
- 71 + 68449 = 68520
Showing the first eight; more decompositions exist.
