Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481142, here are decompositions:

19 + 481123 = 481142
139 + 481003 = 481142
163 + 480979 = 481142
223 + 480919 = 481142
601 + 480541 = 481142
643 + 480499 = 481142
691 + 480451 = 481142
733 + 480409 = 481142

Showing the first eight; more decompositions exist.
