Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548538, here are decompositions:

5 + 548533 = 548538
17 + 548521 = 548538
19 + 548519 = 548538
37 + 548501 = 548538
79 + 548459 = 548538
97 + 548441 = 548538
131 + 548407 = 548538
139 + 548399 = 548538

Showing the first eight; more decompositions exist.
