Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3042, here are decompositions:

5 + 3037 = 3042
19 + 3023 = 3042
23 + 3019 = 3042
31 + 3011 = 3042
41 + 3001 = 3042
43 + 2999 = 3042
71 + 2971 = 3042
73 + 2969 = 3042

Showing the first eight; more decompositions exist.
