Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477362, here are decompositions:

11 + 31477351 = 31477362
13 + 31477349 = 31477362
41 + 31477321 = 31477362
61 + 31477301 = 31477362
71 + 31477291 = 31477362
73 + 31477289 = 31477362
149 + 31477213 = 31477362
181 + 31477181 = 31477362

Showing the first eight; more decompositions exist.
