Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525628, here are decompositions:

19 + 31525609 = 31525628
61 + 31525567 = 31525628
139 + 31525489 = 31525628
151 + 31525477 = 31525628
181 + 31525447 = 31525628
349 + 31525279 = 31525628
367 + 31525261 = 31525628
601 + 31525027 = 31525628

Showing the first eight; more decompositions exist.
