Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547624, here are decompositions:

7 + 31547617 = 31547624
67 + 31547557 = 31547624
211 + 31547413 = 31547624
307 + 31547317 = 31547624
337 + 31547287 = 31547624
421 + 31547203 = 31547624
463 + 31547161 = 31547624
523 + 31547101 = 31547624

Showing the first eight; more decompositions exist.
