Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541932, here are decompositions:

29 + 31541903 = 31541932
41 + 31541891 = 31541932
239 + 31541693 = 31541932
281 + 31541651 = 31541932
449 + 31541483 = 31541932
503 + 31541429 = 31541932
881 + 31541051 = 31541932
911 + 31541021 = 31541932

Showing the first eight; more decompositions exist.
