Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546622, here are decompositions:

31 + 31546591 = 31546622
139 + 31546483 = 31546622
229 + 31546393 = 31546622
271 + 31546351 = 31546622
463 + 31546159 = 31546622
631 + 31545991 = 31546622
859 + 31545763 = 31546622
883 + 31545739 = 31546622

Showing the first eight; more decompositions exist.
