Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509142, here are decompositions:

5 + 509137 = 509142
19 + 509123 = 509142
41 + 509101 = 509142
71 + 509071 = 509142
79 + 509063 = 509142
89 + 509053 = 509142
173 + 508969 = 509142
181 + 508961 = 509142

Showing the first eight; more decompositions exist.
