Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475364, here are decompositions:

23 + 31475341 = 31475364
43 + 31475321 = 31475364
47 + 31475317 = 31475364
113 + 31475251 = 31475364
223 + 31475141 = 31475364
233 + 31475131 = 31475364
257 + 31475107 = 31475364
281 + 31475083 = 31475364

Showing the first eight; more decompositions exist.
