Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103090, here are decompositions:

3 + 103087 = 103090
11 + 103079 = 103090
23 + 103067 = 103090
41 + 103049 = 103090
47 + 103043 = 103090
83 + 103007 = 103090
89 + 103001 = 103090
107 + 102983 = 103090

Showing the first eight; more decompositions exist.
