Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547254, here are decompositions:

23 + 31547231 = 31547254
107 + 31547147 = 31547254
191 + 31547063 = 31547254
251 + 31547003 = 31547254
257 + 31546997 = 31547254
317 + 31546937 = 31547254
593 + 31546661 = 31547254
617 + 31546637 = 31547254

Showing the first eight; more decompositions exist.
