Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78522, here are decompositions:
- 5 + 78517 = 78522
- 11 + 78511 = 78522
- 13 + 78509 = 78522
- 43 + 78479 = 78522
- 83 + 78439 = 78522
- 181 + 78341 = 78522
- 211 + 78311 = 78522
- 239 + 78283 = 78522
Showing the first eight; more decompositions exist.
