Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461932, here are decompositions:

13 + 31461919 = 31461932
109 + 31461823 = 31461932
379 + 31461553 = 31461932
409 + 31461523 = 31461932
571 + 31461361 = 31461932
631 + 31461301 = 31461932
709 + 31461223 = 31461932
739 + 31461193 = 31461932

Showing the first eight; more decompositions exist.
