Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732130, here are decompositions:

7 + 8732123 = 8732130
13 + 8732117 = 8732130
37 + 8732093 = 8732130
59 + 8732071 = 8732130
79 + 8732051 = 8732130
83 + 8732047 = 8732130
101 + 8732029 = 8732130
103 + 8732027 = 8732130

Showing the first eight; more decompositions exist.
