Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508622, here are decompositions:

43 + 31508579 = 31508622
53 + 31508569 = 31508622
73 + 31508549 = 31508622
113 + 31508509 = 31508622
179 + 31508443 = 31508622
263 + 31508359 = 31508622
293 + 31508329 = 31508622
311 + 31508311 = 31508622

Showing the first eight; more decompositions exist.
