Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467822, here are decompositions:

11 + 31467811 = 31467822
13 + 31467809 = 31467822
59 + 31467763 = 31467822
101 + 31467721 = 31467822
103 + 31467719 = 31467822
131 + 31467691 = 31467822
229 + 31467593 = 31467822
233 + 31467589 = 31467822

Showing the first eight; more decompositions exist.
