Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549788, here are decompositions:

37 + 549751 = 549788
97 + 549691 = 549788
139 + 549649 = 549788
181 + 549607 = 549788
199 + 549589 = 549788
241 + 549547 = 549788
271 + 549517 = 549788
277 + 549511 = 549788

Showing the first eight; more decompositions exist.
