Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580634, here are decompositions:

13 + 31580621 = 31580634
17 + 31580617 = 31580634
103 + 31580531 = 31580634
131 + 31580503 = 31580634
157 + 31580477 = 31580634
181 + 31580453 = 31580634
223 + 31580411 = 31580634
307 + 31580327 = 31580634

Showing the first eight; more decompositions exist.
