Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540344, here are decompositions:

5 + 31540339 = 31540344
47 + 31540297 = 31540344
83 + 31540261 = 31540344
103 + 31540241 = 31540344
127 + 31540217 = 31540344
131 + 31540213 = 31540344
137 + 31540207 = 31540344
163 + 31540181 = 31540344

Showing the first eight; more decompositions exist.
