Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549782, here are decompositions:

31 + 549751 = 549782
43 + 549739 = 549782
139 + 549643 = 549782
193 + 549589 = 549782
229 + 549553 = 549782
271 + 549511 = 549782
379 + 549403 = 549782
463 + 549319 = 549782

Showing the first eight; more decompositions exist.
