Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549938, here are decompositions:

61 + 549877 = 549938
199 + 549739 = 549938
271 + 549667 = 549938
331 + 549607 = 549938
349 + 549589 = 549938
421 + 549517 = 549938
457 + 549481 = 549938
547 + 549391 = 549938

Showing the first eight; more decompositions exist.
