Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38722, here are decompositions:
- 11 + 38711 = 38722
- 23 + 38699 = 38722
- 29 + 38693 = 38722
- 53 + 38669 = 38722
- 71 + 38651 = 38722
- 83 + 38639 = 38722
- 113 + 38609 = 38722
- 179 + 38543 = 38722
Showing the first eight; more decompositions exist.
