Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126822, here are decompositions:
- 41 + 126781 = 126822
- 61 + 126761 = 126822
- 71 + 126751 = 126822
- 79 + 126743 = 126822
- 83 + 126739 = 126822
- 89 + 126733 = 126822
- 103 + 126719 = 126822
- 109 + 126713 = 126822
Showing the first eight; more decompositions exist.
