Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546738, here are decompositions:

17 + 31546721 = 31546738
29 + 31546709 = 31546738
101 + 31546637 = 31546738
137 + 31546601 = 31546738
269 + 31546469 = 31546738
281 + 31546457 = 31546738
317 + 31546421 = 31546738
389 + 31546349 = 31546738

Showing the first eight; more decompositions exist.
