Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481628, here are decompositions:

79 + 481549 = 481628
97 + 481531 = 481628
127 + 481501 = 481628
139 + 481489 = 481628
181 + 481447 = 481628
211 + 481417 = 481628
241 + 481387 = 481628
331 + 481297 = 481628

Showing the first eight; more decompositions exist.
