Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462016, here are decompositions:

13 + 31462003 = 31462016
37 + 31461979 = 31462016
67 + 31461949 = 31462016
73 + 31461943 = 31462016
97 + 31461919 = 31462016
193 + 31461823 = 31462016
199 + 31461817 = 31462016
463 + 31461553 = 31462016

Showing the first eight; more decompositions exist.
