Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490622, here are decompositions:

13 + 31490609 = 31490622
29 + 31490593 = 31490622
113 + 31490509 = 31490622
223 + 31490399 = 31490622
239 + 31490383 = 31490622
263 + 31490359 = 31490622
271 + 31490351 = 31490622
283 + 31490339 = 31490622

Showing the first eight; more decompositions exist.
