Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72822, here are decompositions:
- 5 + 72817 = 72822
- 59 + 72763 = 72822
- 83 + 72739 = 72822
- 89 + 72733 = 72822
- 103 + 72719 = 72822
- 149 + 72673 = 72822
- 151 + 72671 = 72822
- 173 + 72649 = 72822
Showing the first eight; more decompositions exist.
