Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585314, here are decompositions:

43 + 31585271 = 31585314
53 + 31585261 = 31585314
97 + 31585217 = 31585314
281 + 31585033 = 31585314
347 + 31584967 = 31585314
353 + 31584961 = 31585314
367 + 31584947 = 31585314
433 + 31584881 = 31585314

Showing the first eight; more decompositions exist.
