Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586604, here are decompositions:

13 + 31586591 = 31586604
61 + 31586543 = 31586604
67 + 31586537 = 31586604
103 + 31586501 = 31586604
107 + 31586497 = 31586604
131 + 31586473 = 31586604
157 + 31586447 = 31586604
197 + 31586407 = 31586604

Showing the first eight; more decompositions exist.
