Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22490, here are decompositions:
- 7 + 22483 = 22490
- 37 + 22453 = 22490
- 43 + 22447 = 22490
- 109 + 22381 = 22490
- 199 + 22291 = 22490
- 211 + 22279 = 22490
- 331 + 22159 = 22490
- 337 + 22153 = 22490
Showing the first eight; more decompositions exist.
