Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472406, here are decompositions:

47 + 31472359 = 31472406
67 + 31472339 = 31472406
113 + 31472293 = 31472406
167 + 31472239 = 31472406
197 + 31472209 = 31472406
223 + 31472183 = 31472406
227 + 31472179 = 31472406
239 + 31472167 = 31472406

Showing the first eight; more decompositions exist.
