Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546624, here are decompositions:

3 + 31546621 = 31546624
23 + 31546601 = 31546624
41 + 31546583 = 31546624
71 + 31546553 = 31546624
167 + 31546457 = 31546624
173 + 31546451 = 31546624
443 + 31546181 = 31546624
617 + 31546007 = 31546624

Showing the first eight; more decompositions exist.
