Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87516, here are decompositions:
- 5 + 87511 = 87516
- 7 + 87509 = 87516
- 43 + 87473 = 87516
- 73 + 87443 = 87516
- 83 + 87433 = 87516
- 89 + 87427 = 87516
- 109 + 87407 = 87516
- 113 + 87403 = 87516
Showing the first eight; more decompositions exist.
