Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87654, here are decompositions:
- 5 + 87649 = 87654
- 11 + 87643 = 87654
- 13 + 87641 = 87654
- 23 + 87631 = 87654
- 31 + 87623 = 87654
- 41 + 87613 = 87654
- 67 + 87587 = 87654
- 71 + 87583 = 87654
Showing the first eight; more decompositions exist.
