Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42788, here are decompositions:
- 37 + 42751 = 42788
- 61 + 42727 = 42788
- 79 + 42709 = 42788
- 139 + 42649 = 42788
- 199 + 42589 = 42788
- 211 + 42577 = 42788
- 331 + 42457 = 42788
- 337 + 42451 = 42788
Showing the first eight; more decompositions exist.
