Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525148, here are decompositions:

157 + 31524991 = 31525148
181 + 31524967 = 31525148
211 + 31524937 = 31525148
541 + 31524607 = 31525148
607 + 31524541 = 31525148
631 + 31524517 = 31525148
877 + 31524271 = 31525148
1231 + 31523917 = 31525148

Showing the first eight; more decompositions exist.
