Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3090, here are decompositions:

7 + 3083 = 3090
11 + 3079 = 3090
23 + 3067 = 3090
29 + 3061 = 3090
41 + 3049 = 3090
53 + 3037 = 3090
67 + 3023 = 3090
71 + 3019 = 3090

Showing the first eight; more decompositions exist.
