Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586926, here are decompositions:

5 + 31586921 = 31586926
23 + 31586903 = 31586926
47 + 31586879 = 31586926
113 + 31586813 = 31586926
227 + 31586699 = 31586926
257 + 31586669 = 31586926
347 + 31586579 = 31586926
383 + 31586543 = 31586926

Showing the first eight; more decompositions exist.
