Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22658, here are decompositions:
- 7 + 22651 = 22658
- 19 + 22639 = 22658
- 37 + 22621 = 22658
- 109 + 22549 = 22658
- 127 + 22531 = 22658
- 157 + 22501 = 22658
- 211 + 22447 = 22658
- 277 + 22381 = 22658
Showing the first eight; more decompositions exist.
