Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72704, here are decompositions:
- 3 + 72701 = 72704
- 31 + 72673 = 72704
- 43 + 72661 = 72704
- 61 + 72643 = 72704
- 127 + 72577 = 72704
- 157 + 72547 = 72704
- 211 + 72493 = 72704
- 223 + 72481 = 72704
Showing the first eight; more decompositions exist.
