Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525848, here are decompositions:

7 + 31525841 = 31525848
31 + 31525817 = 31525848
37 + 31525811 = 31525848
61 + 31525787 = 31525848
71 + 31525777 = 31525848
131 + 31525717 = 31525848
149 + 31525699 = 31525848
191 + 31525657 = 31525848

Showing the first eight; more decompositions exist.
