Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546556, here are decompositions:

3 + 31546553 = 31546556
73 + 31546483 = 31546556
163 + 31546393 = 31546556
277 + 31546279 = 31546556
397 + 31546159 = 31546556
487 + 31546069 = 31546556
1069 + 31545487 = 31546556
1087 + 31545469 = 31546556

Showing the first eight; more decompositions exist.
