Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540586, here are decompositions:

13 + 31540573 = 31540586
97 + 31540489 = 31540586
223 + 31540363 = 31540586
277 + 31540309 = 31540586
373 + 31540213 = 31540586
379 + 31540207 = 31540586
397 + 31540189 = 31540586
439 + 31540147 = 31540586

Showing the first eight; more decompositions exist.
