Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525124, here are decompositions:

3 + 31525121 = 31525124
97 + 31525027 = 31525124
157 + 31524967 = 31525124
331 + 31524793 = 31525124
601 + 31524523 = 31525124
607 + 31524517 = 31525124
823 + 31524301 = 31525124
853 + 31524271 = 31525124

Showing the first eight; more decompositions exist.
