Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42528, here are decompositions:
- 19 + 42509 = 42528
- 29 + 42499 = 42528
- 37 + 42491 = 42528
- 41 + 42487 = 42528
- 61 + 42467 = 42528
- 67 + 42461 = 42528
- 71 + 42457 = 42528
- 131 + 42397 = 42528
Showing the first eight; more decompositions exist.
