Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586096, here are decompositions:

19 + 31586077 = 31586096
37 + 31586059 = 31586096
43 + 31586053 = 31586096
193 + 31585903 = 31586096
313 + 31585783 = 31586096
433 + 31585663 = 31586096
499 + 31585597 = 31586096
547 + 31585549 = 31586096

Showing the first eight; more decompositions exist.
