Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586654, here are decompositions:

7 + 31586647 = 31586654
37 + 31586617 = 31586654
157 + 31586497 = 31586654
181 + 31586473 = 31586654
193 + 31586461 = 31586654
277 + 31586377 = 31586654
367 + 31586287 = 31586654
373 + 31586281 = 31586654

Showing the first eight; more decompositions exist.
