Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525276, here are decompositions:

47 + 31525229 = 31525276
113 + 31525163 = 31525276
149 + 31525127 = 31525276
173 + 31525103 = 31525276
239 + 31525037 = 31525276
269 + 31525007 = 31525276
383 + 31524893 = 31525276
467 + 31524809 = 31525276

Showing the first eight; more decompositions exist.
