Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479822, here are decompositions:

5 + 31479817 = 31479822
19 + 31479803 = 31479822
29 + 31479793 = 31479822
53 + 31479769 = 31479822
79 + 31479743 = 31479822
83 + 31479739 = 31479822
103 + 31479719 = 31479822
151 + 31479671 = 31479822

Showing the first eight; more decompositions exist.
