Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22628, here are decompositions:
- 7 + 22621 = 22628
- 61 + 22567 = 22628
- 79 + 22549 = 22628
- 97 + 22531 = 22628
- 127 + 22501 = 22628
- 181 + 22447 = 22628
- 337 + 22291 = 22628
- 349 + 22279 = 22628
Showing the first eight; more decompositions exist.
