Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586584, here are decompositions:

5 + 31586579 = 31586584
41 + 31586543 = 31586584
47 + 31586537 = 31586584
83 + 31586501 = 31586584
101 + 31586483 = 31586584
137 + 31586447 = 31586584
233 + 31586351 = 31586584
311 + 31586273 = 31586584

Showing the first eight; more decompositions exist.
