Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622684, here are decompositions:

13 + 31622671 = 31622684
43 + 31622641 = 31622684
193 + 31622491 = 31622684
211 + 31622473 = 31622684
307 + 31622377 = 31622684
337 + 31622347 = 31622684
397 + 31622287 = 31622684
571 + 31622113 = 31622684

Showing the first eight; more decompositions exist.
