Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475274, here are decompositions:

23 + 31475251 = 31475274
31 + 31475243 = 31475274
43 + 31475231 = 31475274
163 + 31475111 = 31475274
167 + 31475107 = 31475274
191 + 31475083 = 31475274
277 + 31474997 = 31475274
293 + 31474981 = 31475274

Showing the first eight; more decompositions exist.
