Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586598, here are decompositions:

7 + 31586591 = 31586598
19 + 31586579 = 31586598
61 + 31586537 = 31586598
89 + 31586509 = 31586598
97 + 31586501 = 31586598
101 + 31586497 = 31586598
137 + 31586461 = 31586598
151 + 31586447 = 31586598

Showing the first eight; more decompositions exist.
