Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462752, here are decompositions:

5 + 31462747 = 31462752
23 + 31462729 = 31462752
29 + 31462723 = 31462752
103 + 31462649 = 31462752
149 + 31462603 = 31462752
163 + 31462589 = 31462752
173 + 31462579 = 31462752
179 + 31462573 = 31462752

Showing the first eight; more decompositions exist.
