Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477266, here are decompositions:

53 + 31477213 = 31477266
59 + 31477207 = 31477266
103 + 31477163 = 31477266
167 + 31477099 = 31477266
199 + 31477067 = 31477266
239 + 31477027 = 31477266
307 + 31476959 = 31477266
349 + 31476917 = 31477266

Showing the first eight; more decompositions exist.
