Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481442, here are decompositions:

79 + 481363 = 481442
139 + 481303 = 481442
193 + 481249 = 481442
211 + 481231 = 481442
271 + 481171 = 481442
349 + 481093 = 481442
421 + 481021 = 481442
433 + 481009 = 481442

Showing the first eight; more decompositions exist.
