Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543274, here are decompositions:

31 + 31543243 = 31543274
43 + 31543231 = 31543274
67 + 31543207 = 31543274
283 + 31542991 = 31543274
307 + 31542967 = 31543274
331 + 31542943 = 31543274
337 + 31542937 = 31543274
397 + 31542877 = 31543274

Showing the first eight; more decompositions exist.
