Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540346, here are decompositions:

3 + 31540343 = 31540346
7 + 31540339 = 31540346
37 + 31540309 = 31540346
139 + 31540207 = 31540346
157 + 31540189 = 31540346
199 + 31540147 = 31540346
223 + 31540123 = 31540346
283 + 31540063 = 31540346

Showing the first eight; more decompositions exist.
