Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465476, here are decompositions:

17 + 31465459 = 31465476
59 + 31465417 = 31465476
113 + 31465363 = 31465476
167 + 31465309 = 31465476
233 + 31465243 = 31465476
283 + 31465193 = 31465476
293 + 31465183 = 31465476
347 + 31465129 = 31465476

Showing the first eight; more decompositions exist.
