Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539438, here are decompositions:

37 + 539401 = 539438
127 + 539311 = 539438
271 + 539167 = 539438
331 + 539107 = 539438
337 + 539101 = 539438
349 + 539089 = 539438
499 + 538939 = 539438
661 + 538777 = 539438

Showing the first eight; more decompositions exist.
