Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585832, here are decompositions:

283 + 31585549 = 31585832
331 + 31585501 = 31585832
373 + 31585459 = 31585832
379 + 31585453 = 31585832
433 + 31585399 = 31585832
463 + 31585369 = 31585832
571 + 31585261 = 31585832
643 + 31585189 = 31585832

Showing the first eight; more decompositions exist.
