Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540026, here are decompositions:

13 + 31540013 = 31540026
17 + 31540009 = 31540026
19 + 31540007 = 31540026
59 + 31539967 = 31540026
137 + 31539889 = 31540026
163 + 31539863 = 31540026
263 + 31539763 = 31540026
269 + 31539757 = 31540026

Showing the first eight; more decompositions exist.
