Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472346, here are decompositions:

7 + 31472339 = 31472346
53 + 31472293 = 31472346
107 + 31472239 = 31472346
137 + 31472209 = 31472346
163 + 31472183 = 31472346
167 + 31472179 = 31472346
179 + 31472167 = 31472346
193 + 31472153 = 31472346

Showing the first eight; more decompositions exist.
