Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475622, here are decompositions:

11 + 31475611 = 31475622
23 + 31475599 = 31475622
41 + 31475581 = 31475622
43 + 31475579 = 31475622
131 + 31475491 = 31475622
151 + 31475471 = 31475622
163 + 31475459 = 31475622
179 + 31475443 = 31475622

Showing the first eight; more decompositions exist.
