Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585262, here are decompositions:

73 + 31585189 = 31585262
103 + 31585159 = 31585262
229 + 31585033 = 31585262
409 + 31584853 = 31585262
433 + 31584829 = 31585262
439 + 31584823 = 31585262
661 + 31584601 = 31585262
739 + 31584523 = 31585262

Showing the first eight; more decompositions exist.
