Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477364, here are decompositions:

13 + 31477351 = 31477364
43 + 31477321 = 31477364
73 + 31477291 = 31477364
151 + 31477213 = 31477364
157 + 31477207 = 31477364
223 + 31477141 = 31477364
307 + 31477057 = 31477364
313 + 31477051 = 31477364

Showing the first eight; more decompositions exist.
