Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471326, here are decompositions:

37 + 31471289 = 31471326
109 + 31471217 = 31471326
113 + 31471213 = 31471326
179 + 31471147 = 31471326
233 + 31471093 = 31471326
283 + 31471043 = 31471326
349 + 31470977 = 31471326
373 + 31470953 = 31471326

Showing the first eight; more decompositions exist.
