Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481144, here are decompositions:

3 + 481141 = 481144
11 + 481133 = 481144
47 + 481097 = 481144
71 + 481073 = 481144
101 + 481043 = 481144
233 + 480911 = 481144
263 + 480881 = 481144
317 + 480827 = 481144

Showing the first eight; more decompositions exist.
