Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547366, here are decompositions:

79 + 31547287 = 31547366
157 + 31547209 = 31547366
163 + 31547203 = 31547366
223 + 31547143 = 31547366
379 + 31546987 = 31547366
397 + 31546969 = 31547366
457 + 31546909 = 31547366
523 + 31546843 = 31547366

Showing the first eight; more decompositions exist.
