Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548618, here are decompositions:

61 + 548557 = 548618
97 + 548521 = 548618
157 + 548461 = 548618
211 + 548407 = 548618
271 + 548347 = 548618
379 + 548239 = 548618
397 + 548221 = 548618
619 + 547999 = 548618

Showing the first eight; more decompositions exist.
