Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481220, here are decompositions:

13 + 481207 = 481220
43 + 481177 = 481220
67 + 481153 = 481220
73 + 481147 = 481220
79 + 481141 = 481220
97 + 481123 = 481220
127 + 481093 = 481220
199 + 481021 = 481220

Showing the first eight; more decompositions exist.
