Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30528, here are decompositions:
- 11 + 30517 = 30528
- 19 + 30509 = 30528
- 31 + 30497 = 30528
- 37 + 30491 = 30528
- 59 + 30469 = 30528
- 61 + 30467 = 30528
- 79 + 30449 = 30528
- 97 + 30431 = 30528
Showing the first eight; more decompositions exist.
