Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537518, here are decompositions:

139 + 537379 = 537518
211 + 537307 = 537518
277 + 537241 = 537518
337 + 537181 = 537518
349 + 537169 = 537518
439 + 537079 = 537518
547 + 536971 = 537518
571 + 536947 = 537518

Showing the first eight; more decompositions exist.
