Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540226, here are decompositions:

13 + 31540213 = 31540226
19 + 31540207 = 31540226
37 + 31540189 = 31540226
79 + 31540147 = 31540226
103 + 31540123 = 31540226
127 + 31540099 = 31540226
163 + 31540063 = 31540226
337 + 31539889 = 31540226

Showing the first eight; more decompositions exist.
