Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540326, here are decompositions:

17 + 31540309 = 31540326
29 + 31540297 = 31540326
109 + 31540217 = 31540326
113 + 31540213 = 31540326
137 + 31540189 = 31540326
163 + 31540163 = 31540326
179 + 31540147 = 31540326
227 + 31540099 = 31540326

Showing the first eight; more decompositions exist.
