Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509642, here are decompositions:

19 + 509623 = 509642
61 + 509581 = 509642
73 + 509569 = 509642
79 + 509563 = 509642
193 + 509449 = 509642
229 + 509413 = 509642
283 + 509359 = 509642
313 + 509329 = 509642

Showing the first eight; more decompositions exist.
