Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549638, here are decompositions:

31 + 549607 = 549638
127 + 549511 = 549638
157 + 549481 = 549638
307 + 549331 = 549638
379 + 549259 = 549638
409 + 549229 = 549638
499 + 549139 = 549638
541 + 549097 = 549638

Showing the first eight; more decompositions exist.
