Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622718, here are decompositions:

5 + 31622713 = 31622718
19 + 31622699 = 31622718
31 + 31622687 = 31622718
47 + 31622671 = 31622718
89 + 31622629 = 31622718
139 + 31622579 = 31622718
181 + 31622537 = 31622718
199 + 31622519 = 31622718

Showing the first eight; more decompositions exist.
