Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72722, here are decompositions:
- 3 + 72719 = 72722
- 43 + 72679 = 72722
- 61 + 72661 = 72722
- 73 + 72649 = 72722
- 79 + 72643 = 72722
- 109 + 72613 = 72722
- 163 + 72559 = 72722
- 229 + 72493 = 72722
Showing the first eight; more decompositions exist.
