Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525382, here are decompositions:

3 + 31525379 = 31525382
103 + 31525279 = 31525382
139 + 31525243 = 31525382
181 + 31525201 = 31525382
199 + 31525183 = 31525382
619 + 31524763 = 31525382
661 + 31524721 = 31525382
709 + 31524673 = 31525382

Showing the first eight; more decompositions exist.
