Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622080, here are decompositions:

101 + 31621979 = 31622080
131 + 31621949 = 31622080
179 + 31621901 = 31622080
233 + 31621847 = 31622080
401 + 31621679 = 31622080
419 + 31621661 = 31622080
443 + 31621637 = 31622080
449 + 31621631 = 31622080

Showing the first eight; more decompositions exist.
