Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127822, here are decompositions:
- 3 + 127819 = 127822
- 5 + 127817 = 127822
- 41 + 127781 = 127822
- 59 + 127763 = 127822
- 83 + 127739 = 127822
- 89 + 127733 = 127822
- 113 + 127709 = 127822
- 131 + 127691 = 127822
Showing the first eight; more decompositions exist.
