Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622598, here are decompositions:

19 + 31622579 = 31622598
61 + 31622537 = 31622598
79 + 31622519 = 31622598
89 + 31622509 = 31622598
107 + 31622491 = 31622598
131 + 31622467 = 31622598
229 + 31622369 = 31622598
251 + 31622347 = 31622598

Showing the first eight; more decompositions exist.
