Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537638, here are decompositions:

307 + 537331 = 537638
331 + 537307 = 537638
397 + 537241 = 537638
457 + 537181 = 537638
547 + 537091 = 537638
571 + 537067 = 537638
601 + 537037 = 537638
631 + 537007 = 537638

Showing the first eight; more decompositions exist.
