Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462770, here are decompositions:

11 + 31462759 = 31462770
13 + 31462757 = 31462770
19 + 31462751 = 31462770
23 + 31462747 = 31462770
41 + 31462729 = 31462770
47 + 31462723 = 31462770
167 + 31462603 = 31462770
179 + 31462591 = 31462770

Showing the first eight; more decompositions exist.
