Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494622, here are decompositions:

11 + 31494611 = 31494622
41 + 31494581 = 31494622
113 + 31494509 = 31494622
179 + 31494443 = 31494622
191 + 31494431 = 31494622
233 + 31494389 = 31494622
359 + 31494263 = 31494622
443 + 31494179 = 31494622

Showing the first eight; more decompositions exist.
