Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156772, here are decompositions:
- 23 + 156749 = 156772
- 53 + 156719 = 156772
- 89 + 156683 = 156772
- 101 + 156671 = 156772
- 113 + 156659 = 156772
- 131 + 156641 = 156772
- 149 + 156623 = 156772
- 179 + 156593 = 156772
Showing the first eight; more decompositions exist.
