Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42520, here are decompositions:
- 11 + 42509 = 42520
- 29 + 42491 = 42520
- 47 + 42473 = 42520
- 53 + 42467 = 42520
- 59 + 42461 = 42520
- 83 + 42437 = 42520
- 113 + 42407 = 42520
- 197 + 42323 = 42520
Showing the first eight; more decompositions exist.
