Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525806, here are decompositions:

7 + 31525799 = 31525806
19 + 31525787 = 31525806
23 + 31525783 = 31525806
29 + 31525777 = 31525806
43 + 31525763 = 31525806
83 + 31525723 = 31525806
89 + 31525717 = 31525806
107 + 31525699 = 31525806

Showing the first eight; more decompositions exist.
