Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42522, here are decompositions:
- 13 + 42509 = 42522
- 23 + 42499 = 42522
- 31 + 42491 = 42522
- 59 + 42463 = 42522
- 61 + 42461 = 42522
- 71 + 42451 = 42522
- 79 + 42443 = 42522
- 89 + 42433 = 42522
Showing the first eight; more decompositions exist.
