Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586734, here are decompositions:

17 + 31586717 = 31586734
107 + 31586627 = 31586734
191 + 31586543 = 31586734
197 + 31586537 = 31586734
233 + 31586501 = 31586734
251 + 31586483 = 31586734
383 + 31586351 = 31586734
461 + 31586273 = 31586734

Showing the first eight; more decompositions exist.
