Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525352, here are decompositions:

73 + 31525279 = 31525352
109 + 31525243 = 31525352
139 + 31525213 = 31525352
151 + 31525201 = 31525352
631 + 31524721 = 31525352
709 + 31524643 = 31525352
811 + 31524541 = 31525352
829 + 31524523 = 31525352

Showing the first eight; more decompositions exist.
