Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481444, here are decompositions:

11 + 481433 = 481444
71 + 481373 = 481444
101 + 481343 = 481444
137 + 481307 = 481444
233 + 481211 = 481444
263 + 481181 = 481444
311 + 481133 = 481444
347 + 481097 = 481444

Showing the first eight; more decompositions exist.
