Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509130, here are decompositions:

7 + 509123 = 509130
29 + 509101 = 509130
43 + 509087 = 509130
59 + 509071 = 509130
67 + 509063 = 509130
103 + 509027 = 509130
107 + 509023 = 509130
157 + 508973 = 509130

Showing the first eight; more decompositions exist.
