Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87998, here are decompositions:
- 7 + 87991 = 87998
- 37 + 87961 = 87998
- 67 + 87931 = 87998
- 277 + 87721 = 87998
- 307 + 87691 = 87998
- 349 + 87649 = 87998
- 367 + 87631 = 87998
- 409 + 87589 = 87998
Showing the first eight; more decompositions exist.
