Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87504, here are decompositions:
- 13 + 87491 = 87504
- 23 + 87481 = 87504
- 31 + 87473 = 87504
- 61 + 87443 = 87504
- 71 + 87433 = 87504
- 83 + 87421 = 87504
- 97 + 87407 = 87504
- 101 + 87403 = 87504
Showing the first eight; more decompositions exist.
