Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477352, here are decompositions:

3 + 31477349 = 31477352
31 + 31477321 = 31477352
61 + 31477291 = 31477352
139 + 31477213 = 31477352
211 + 31477141 = 31477352
241 + 31477111 = 31477352
331 + 31477021 = 31477352
421 + 31476931 = 31477352

Showing the first eight; more decompositions exist.
