Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548478, here are decompositions:

17 + 548461 = 548478
19 + 548459 = 548478
37 + 548441 = 548478
61 + 548417 = 548478
71 + 548407 = 548478
79 + 548399 = 548478
107 + 548371 = 548478
127 + 548351 = 548478

Showing the first eight; more decompositions exist.
