Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87684, here are decompositions:
- 5 + 87679 = 87684
- 13 + 87671 = 87684
- 41 + 87643 = 87684
- 43 + 87641 = 87684
- 53 + 87631 = 87684
- 61 + 87623 = 87684
- 71 + 87613 = 87684
- 97 + 87587 = 87684
Showing the first eight; more decompositions exist.
