Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465422, here are decompositions:

5 + 31465417 = 31465422
31 + 31465391 = 31465422
59 + 31465363 = 31465422
101 + 31465321 = 31465422
113 + 31465309 = 31465422
179 + 31465243 = 31465422
199 + 31465223 = 31465422
229 + 31465193 = 31465422

Showing the first eight; more decompositions exist.
