Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480634, here are decompositions:

13 + 31480621 = 31480634
127 + 31480507 = 31480634
193 + 31480441 = 31480634
433 + 31480201 = 31480634
613 + 31480021 = 31480634
673 + 31479961 = 31480634
877 + 31479757 = 31480634
937 + 31479697 = 31480634

Showing the first eight; more decompositions exist.
