Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477358, here are decompositions:

7 + 31477351 = 31477358
37 + 31477321 = 31477358
67 + 31477291 = 31477358
151 + 31477207 = 31477358
307 + 31477051 = 31477358
331 + 31477027 = 31477358
337 + 31477021 = 31477358
487 + 31476871 = 31477358

Showing the first eight; more decompositions exist.
