Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78528, here are decompositions:
- 11 + 78517 = 78528
- 17 + 78511 = 78528
- 19 + 78509 = 78528
- 31 + 78497 = 78528
- 41 + 78487 = 78528
- 61 + 78467 = 78528
- 89 + 78439 = 78528
- 101 + 78427 = 78528
Showing the first eight; more decompositions exist.
