Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467020, here are decompositions:

31 + 31466989 = 31467020
43 + 31466977 = 31467020
127 + 31466893 = 31467020
163 + 31466857 = 31467020
199 + 31466821 = 31467020
229 + 31466791 = 31467020
271 + 31466749 = 31467020
307 + 31466713 = 31467020

Showing the first eight; more decompositions exist.
