Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622686, here are decompositions:

3 + 31622683 = 31622686
23 + 31622663 = 31622686
107 + 31622579 = 31622686
149 + 31622537 = 31622686
167 + 31622519 = 31622686
257 + 31622429 = 31622686
317 + 31622369 = 31622686
449 + 31622237 = 31622686

Showing the first eight; more decompositions exist.
