Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472194, here are decompositions:

3 + 31472191 = 31472194
11 + 31472183 = 31472194
41 + 31472153 = 31472194
71 + 31472123 = 31472194
191 + 31472003 = 31472194
227 + 31471967 = 31472194
293 + 31471901 = 31472194
311 + 31471883 = 31472194

Showing the first eight; more decompositions exist.
