Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465622, here are decompositions:

3 + 31465619 = 31465622
43 + 31465579 = 31465622
61 + 31465561 = 31465622
163 + 31465459 = 31465622
313 + 31465309 = 31465622
379 + 31465243 = 31465622
439 + 31465183 = 31465622
499 + 31465123 = 31465622

Showing the first eight; more decompositions exist.
