Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509738, here are decompositions:

7 + 509731 = 509738
79 + 509659 = 509738
157 + 509581 = 509738
181 + 509557 = 509738
349 + 509389 = 509738
379 + 509359 = 509738
409 + 509329 = 509738
421 + 509317 = 509738

Showing the first eight; more decompositions exist.
