Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540646, here are decompositions:

17 + 540629 = 540646
47 + 540599 = 540646
59 + 540587 = 540646
89 + 540557 = 540646
107 + 540539 = 540646
137 + 540509 = 540646
257 + 540389 = 540646
263 + 540383 = 540646

Showing the first eight; more decompositions exist.
