Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465506, here are decompositions:

47 + 31465459 = 31465506
89 + 31465417 = 31465506
197 + 31465309 = 31465506
263 + 31465243 = 31465506
283 + 31465223 = 31465506
313 + 31465193 = 31465506
353 + 31465153 = 31465506
383 + 31465123 = 31465506

Showing the first eight; more decompositions exist.
