Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525106, here are decompositions:

3 + 31525103 = 31525106
79 + 31525027 = 31525106
139 + 31524967 = 31525106
313 + 31524793 = 31525106
433 + 31524673 = 31525106
463 + 31524643 = 31525106
499 + 31524607 = 31525106
607 + 31524499 = 31525106

Showing the first eight; more decompositions exist.
