Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87534, here are decompositions:
- 11 + 87523 = 87534
- 17 + 87517 = 87534
- 23 + 87511 = 87534
- 43 + 87491 = 87534
- 53 + 87481 = 87534
- 61 + 87473 = 87534
- 101 + 87433 = 87534
- 107 + 87427 = 87534
Showing the first eight; more decompositions exist.
