Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481720, here are decompositions:

23 + 481697 = 481720
47 + 481673 = 481720
53 + 481667 = 481720
101 + 481619 = 481720
131 + 481589 = 481720
149 + 481571 = 481720
251 + 481469 = 481720
311 + 481409 = 481720

Showing the first eight; more decompositions exist.
