Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461962, here are decompositions:

13 + 31461949 = 31461962
19 + 31461943 = 31461962
43 + 31461919 = 31461962
139 + 31461823 = 31461962
151 + 31461811 = 31461962
199 + 31461763 = 31461962
409 + 31461553 = 31461962
439 + 31461523 = 31461962

Showing the first eight; more decompositions exist.
