Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586336, here are decompositions:

79 + 31586257 = 31586336
277 + 31586059 = 31586336
283 + 31586053 = 31586336
373 + 31585963 = 31586336
433 + 31585903 = 31586336
487 + 31585849 = 31586336
499 + 31585837 = 31586336
673 + 31585663 = 31586336

Showing the first eight; more decompositions exist.
