Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498022, here are decompositions:

13 + 31498009 = 31498022
19 + 31498003 = 31498022
43 + 31497979 = 31498022
139 + 31497883 = 31498022
151 + 31497871 = 31498022
163 + 31497859 = 31498022
271 + 31497751 = 31498022
349 + 31497673 = 31498022

Showing the first eight; more decompositions exist.
