Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622698, here are decompositions:

5 + 31622693 = 31622698
11 + 31622687 = 31622698
179 + 31622519 = 31622698
269 + 31622429 = 31622698
461 + 31622237 = 31622698
491 + 31622207 = 31622698
509 + 31622189 = 31622698
557 + 31622141 = 31622698

Showing the first eight; more decompositions exist.
