Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509126, here are decompositions:

3 + 509123 = 509126
73 + 509053 = 509126
103 + 509023 = 509126
139 + 508987 = 509126
157 + 508969 = 509126
223 + 508903 = 509126
337 + 508789 = 509126
433 + 508693 = 509126

Showing the first eight; more decompositions exist.
