Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540688, here are decompositions:

11 + 540677 = 540688
59 + 540629 = 540688
89 + 540599 = 540688
101 + 540587 = 540688
131 + 540557 = 540688
149 + 540539 = 540688
179 + 540509 = 540688
227 + 540461 = 540688

Showing the first eight; more decompositions exist.
