Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546000, here are decompositions:

41 + 31545959 = 31546000
47 + 31545953 = 31546000
113 + 31545887 = 31546000
251 + 31545749 = 31546000
257 + 31545743 = 31546000
263 + 31545737 = 31546000
359 + 31545641 = 31546000
389 + 31545611 = 31546000

Showing the first eight; more decompositions exist.
