Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622608, here are decompositions:

29 + 31622579 = 31622608
71 + 31622537 = 31622608
89 + 31622519 = 31622608
179 + 31622429 = 31622608
239 + 31622369 = 31622608
401 + 31622207 = 31622608
419 + 31622189 = 31622608
461 + 31622147 = 31622608

Showing the first eight; more decompositions exist.
