Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547622, here are decompositions:

5 + 31547617 = 31547622
13 + 31547609 = 31547622
31 + 31547591 = 31547622
83 + 31547539 = 31547622
103 + 31547519 = 31547622
151 + 31547471 = 31547622
163 + 31547459 = 31547622
173 + 31547449 = 31547622

Showing the first eight; more decompositions exist.
