Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465294, here are decompositions:

5 + 31465289 = 31465294
71 + 31465223 = 31465294
101 + 31465193 = 31465294
233 + 31465061 = 31465294
347 + 31464947 = 31465294
353 + 31464941 = 31465294
467 + 31464827 = 31465294
563 + 31464731 = 31465294

Showing the first eight; more decompositions exist.
