Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478176, here are decompositions:

3 + 31478173 = 31478176
5 + 31478171 = 31478176
29 + 31478147 = 31478176
47 + 31478129 = 31478176
239 + 31477937 = 31478176
269 + 31477907 = 31478176
293 + 31477883 = 31478176
383 + 31477793 = 31478176

Showing the first eight; more decompositions exist.
