Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525788, here are decompositions:

5 + 31525783 = 31525788
11 + 31525777 = 31525788
17 + 31525771 = 31525788
71 + 31525717 = 31525788
89 + 31525699 = 31525788
101 + 31525687 = 31525788
131 + 31525657 = 31525788
137 + 31525651 = 31525788

Showing the first eight; more decompositions exist.
