Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547436, here are decompositions:

23 + 31547413 = 31547436
79 + 31547357 = 31547436
97 + 31547339 = 31547436
139 + 31547297 = 31547436
149 + 31547287 = 31547436
227 + 31547209 = 31547436
233 + 31547203 = 31547436
293 + 31547143 = 31547436

Showing the first eight; more decompositions exist.
