Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525734, here are decompositions:

11 + 31525723 = 31525734
17 + 31525717 = 31525734
47 + 31525687 = 31525734
83 + 31525651 = 31525734
127 + 31525607 = 31525734
131 + 31525603 = 31525734
167 + 31525567 = 31525734
181 + 31525553 = 31525734

Showing the first eight; more decompositions exist.
