Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156684, here are decompositions:
- 5 + 156679 = 156684
- 7 + 156677 = 156684
- 13 + 156671 = 156684
- 43 + 156641 = 156684
- 53 + 156631 = 156684
- 61 + 156623 = 156684
- 83 + 156601 = 156684
- 107 + 156577 = 156684
Showing the first eight; more decompositions exist.
