Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170748, here are decompositions:
- 7 + 170741 = 170748
- 37 + 170711 = 170748
- 41 + 170707 = 170748
- 47 + 170701 = 170748
- 59 + 170689 = 170748
- 79 + 170669 = 170748
- 101 + 170647 = 170748
- 107 + 170641 = 170748
Showing the first eight; more decompositions exist.
