Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509148, here are decompositions:

11 + 509137 = 509148
47 + 509101 = 509148
61 + 509087 = 509148
179 + 508969 = 509148
191 + 508957 = 509148
197 + 508951 = 509148
229 + 508919 = 509148
239 + 508909 = 509148

Showing the first eight; more decompositions exist.
