Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465434, here are decompositions:

17 + 31465417 = 31465434
43 + 31465391 = 31465434
71 + 31465363 = 31465434
113 + 31465321 = 31465434
191 + 31465243 = 31465434
211 + 31465223 = 31465434
241 + 31465193 = 31465434
251 + 31465183 = 31465434

Showing the first eight; more decompositions exist.
