Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509144, here are decompositions:

7 + 509137 = 509144
43 + 509101 = 509144
73 + 509071 = 509144
157 + 508987 = 509144
193 + 508951 = 509144
241 + 508903 = 509144
277 + 508867 = 509144
373 + 508771 = 509144

Showing the first eight; more decompositions exist.
