Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460886, here are decompositions:

7 + 31460879 = 31460886
13 + 31460873 = 31460886
47 + 31460839 = 31460886
53 + 31460833 = 31460886
103 + 31460783 = 31460886
157 + 31460729 = 31460886
229 + 31460657 = 31460886
239 + 31460647 = 31460886

Showing the first eight; more decompositions exist.
