Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622560, here are decompositions:

23 + 31622537 = 31622560
41 + 31622519 = 31622560
131 + 31622429 = 31622560
191 + 31622369 = 31622560
353 + 31622207 = 31622560
419 + 31622141 = 31622560
479 + 31622081 = 31622560
659 + 31621901 = 31622560

Showing the first eight; more decompositions exist.
