Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42774, here are decompositions:

7 + 42767 = 42774
23 + 42751 = 42774
31 + 42743 = 42774
37 + 42737 = 42774
47 + 42727 = 42774
71 + 42703 = 42774
73 + 42701 = 42774
97 + 42677 = 42774

Showing the first eight; more decompositions exist.
