Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492070, here are decompositions:

3 + 31492067 = 31492070
19 + 31492051 = 31492070
37 + 31492033 = 31492070
157 + 31491913 = 31492070
229 + 31491841 = 31492070
277 + 31491793 = 31492070
283 + 31491787 = 31492070
373 + 31491697 = 31492070

Showing the first eight; more decompositions exist.
