Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479022, here are decompositions:

5 + 31479017 = 31479022
53 + 31478969 = 31479022
89 + 31478933 = 31479022
191 + 31478831 = 31479022
383 + 31478639 = 31479022
593 + 31478429 = 31479022
941 + 31478081 = 31479022
1031 + 31477991 = 31479022

Showing the first eight; more decompositions exist.
