Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87522, here are decompositions:
- 5 + 87517 = 87522
- 11 + 87511 = 87522
- 13 + 87509 = 87522
- 31 + 87491 = 87522
- 41 + 87481 = 87522
- 79 + 87443 = 87522
- 89 + 87433 = 87522
- 101 + 87421 = 87522
Showing the first eight; more decompositions exist.
