Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585862, here are decompositions:

13 + 31585849 = 31585862
79 + 31585783 = 31585862
199 + 31585663 = 31585862
283 + 31585579 = 31585862
313 + 31585549 = 31585862
409 + 31585453 = 31585862
421 + 31585441 = 31585862
463 + 31585399 = 31585862

Showing the first eight; more decompositions exist.
