Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462788, here are decompositions:

17 + 31462771 = 31462788
29 + 31462759 = 31462788
31 + 31462757 = 31462788
37 + 31462751 = 31462788
41 + 31462747 = 31462788
59 + 31462729 = 31462788
139 + 31462649 = 31462788
179 + 31462609 = 31462788

Showing the first eight; more decompositions exist.
