Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525326, here are decompositions:

37 + 31525289 = 31525326
43 + 31525283 = 31525326
47 + 31525279 = 31525326
59 + 31525267 = 31525326
83 + 31525243 = 31525326
97 + 31525229 = 31525326
113 + 31525213 = 31525326
149 + 31525177 = 31525326

Showing the first eight; more decompositions exist.
