Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637090, here are decompositions:

23 + 8637067 = 8637090
29 + 8637061 = 8637090
31 + 8637059 = 8637090
37 + 8637053 = 8637090
73 + 8637017 = 8637090
83 + 8637007 = 8637090
101 + 8636989 = 8637090
103 + 8636987 = 8637090

Showing the first eight; more decompositions exist.
