Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525718, here are decompositions:

19 + 31525699 = 31525718
31 + 31525687 = 31525718
61 + 31525657 = 31525718
67 + 31525651 = 31525718
109 + 31525609 = 31525718
151 + 31525567 = 31525718
181 + 31525537 = 31525718
229 + 31525489 = 31525718

Showing the first eight; more decompositions exist.
