Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586794, here are decompositions:

3 + 31586791 = 31586794
167 + 31586627 = 31586794
251 + 31586543 = 31586794
257 + 31586537 = 31586794
293 + 31586501 = 31586794
311 + 31586483 = 31586794
347 + 31586447 = 31586794
443 + 31586351 = 31586794

Showing the first eight; more decompositions exist.
