Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 539972, here are decompositions:

73 + 539899 = 539972
109 + 539863 = 539972
211 + 539761 = 539972
229 + 539743 = 539972
331 + 539641 = 539972
439 + 539533 = 539972
463 + 539509 = 539972
523 + 539449 = 539972

Showing the first eight; more decompositions exist.
