Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75998, here are decompositions:
- 7 + 75991 = 75998
- 19 + 75979 = 75998
- 31 + 75967 = 75998
- 61 + 75937 = 75998
- 67 + 75931 = 75998
- 211 + 75787 = 75998
- 277 + 75721 = 75998
- 379 + 75619 = 75998
Showing the first eight; more decompositions exist.
