Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568610, here are decompositions:

23 + 31568587 = 31568610
67 + 31568543 = 31568610
71 + 31568539 = 31568610
83 + 31568527 = 31568610
113 + 31568497 = 31568610
191 + 31568419 = 31568610
193 + 31568417 = 31568610
197 + 31568413 = 31568610

Showing the first eight; more decompositions exist.
