Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450752, here are decompositions:

13 + 31450739 = 31450752
29 + 31450723 = 31450752
31 + 31450721 = 31450752
131 + 31450621 = 31450752
139 + 31450613 = 31450752
149 + 31450603 = 31450752
163 + 31450589 = 31450752
173 + 31450579 = 31450752

Showing the first eight; more decompositions exist.
