Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492016, here are decompositions:

103 + 31491913 = 31492016
223 + 31491793 = 31492016
229 + 31491787 = 31492016
337 + 31491679 = 31492016
379 + 31491637 = 31492016
397 + 31491619 = 31492016
547 + 31491469 = 31492016
709 + 31491307 = 31492016

Showing the first eight; more decompositions exist.
