Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481156, here are decompositions:

3 + 481153 = 481156
23 + 481133 = 481156
47 + 481109 = 481156
59 + 481097 = 481156
83 + 481073 = 481156
89 + 481067 = 481156
113 + 481043 = 481156
167 + 480989 = 481156

Showing the first eight; more decompositions exist.
