Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548490, here are decompositions:

29 + 548461 = 548490
31 + 548459 = 548490
37 + 548453 = 548490
67 + 548423 = 548490
73 + 548417 = 548490
83 + 548407 = 548490
97 + 548393 = 548490
127 + 548363 = 548490

Showing the first eight; more decompositions exist.
