Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585292, here are decompositions:

3 + 31585289 = 31585292
31 + 31585261 = 31585292
103 + 31585189 = 31585292
199 + 31585093 = 31585292
331 + 31584961 = 31585292
439 + 31584853 = 31585292
463 + 31584829 = 31585292
523 + 31584769 = 31585292

Showing the first eight; more decompositions exist.
