Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87672, here are decompositions:
- 23 + 87649 = 87672
- 29 + 87643 = 87672
- 31 + 87641 = 87672
- 41 + 87631 = 87672
- 43 + 87629 = 87672
- 59 + 87613 = 87672
- 83 + 87589 = 87672
- 89 + 87583 = 87672
Showing the first eight; more decompositions exist.
