Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586798, here are decompositions:

7 + 31586791 = 31586798
79 + 31586719 = 31586798
109 + 31586689 = 31586798
127 + 31586671 = 31586798
151 + 31586647 = 31586798
181 + 31586617 = 31586798
337 + 31586461 = 31586798
421 + 31586377 = 31586798

Showing the first eight; more decompositions exist.
