Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585058, here are decompositions:

97 + 31584961 = 31585058
151 + 31584907 = 31585058
157 + 31584901 = 31585058
229 + 31584829 = 31585058
457 + 31584601 = 31585058
499 + 31584559 = 31585058
577 + 31584481 = 31585058
601 + 31584457 = 31585058

Showing the first eight; more decompositions exist.
