Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622658, here are decompositions:

17 + 31622641 = 31622658
29 + 31622629 = 31622658
59 + 31622599 = 31622658
79 + 31622579 = 31622658
139 + 31622519 = 31622658
149 + 31622509 = 31622658
167 + 31622491 = 31622658
191 + 31622467 = 31622658

Showing the first eight; more decompositions exist.
