Goldbach decomposition

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.
