Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525386, here are decompositions:

7 + 31525379 = 31525386
19 + 31525367 = 31525386
43 + 31525343 = 31525386
97 + 31525289 = 31525386
103 + 31525283 = 31525386
107 + 31525279 = 31525386
157 + 31525229 = 31525386
173 + 31525213 = 31525386

Showing the first eight; more decompositions exist.
