Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481212, here are decompositions:

5 + 481207 = 481212
13 + 481199 = 481212
31 + 481181 = 481212
41 + 481171 = 481212
59 + 481153 = 481212
71 + 481141 = 481212
79 + 481133 = 481212
89 + 481123 = 481212

Showing the first eight; more decompositions exist.
