Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586606, here are decompositions:

97 + 31586509 = 31586606
109 + 31586497 = 31586606
199 + 31586407 = 31586606
229 + 31586377 = 31586606
349 + 31586257 = 31586606
547 + 31586059 = 31586606
643 + 31585963 = 31586606
757 + 31585849 = 31586606

Showing the first eight; more decompositions exist.
