Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15522, here are decompositions:
- 11 + 15511 = 15522
- 29 + 15493 = 15522
- 61 + 15461 = 15522
- 71 + 15451 = 15522
- 79 + 15443 = 15522
- 83 + 15439 = 15522
- 109 + 15413 = 15522
- 131 + 15391 = 15522
Showing the first eight; more decompositions exist.
