Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586608, here are decompositions:

17 + 31586591 = 31586608
29 + 31586579 = 31586608
71 + 31586537 = 31586608
107 + 31586501 = 31586608
257 + 31586351 = 31586608
269 + 31586339 = 31586608
461 + 31586147 = 31586608
467 + 31586141 = 31586608

Showing the first eight; more decompositions exist.
