Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509180, here are decompositions:

31 + 509149 = 509180
43 + 509137 = 509180
79 + 509101 = 509180
109 + 509071 = 509180
127 + 509053 = 509180
157 + 509023 = 509180
193 + 508987 = 509180
211 + 508969 = 509180

Showing the first eight; more decompositions exist.
