Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548742, here are decompositions:

23 + 548719 = 548742
71 + 548671 = 548742
113 + 548629 = 548742
151 + 548591 = 548742
163 + 548579 = 548742
199 + 548543 = 548742
223 + 548519 = 548742
239 + 548503 = 548742

Showing the first eight; more decompositions exist.
