Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622360, here are decompositions:

13 + 31622347 = 31622360
67 + 31622293 = 31622360
73 + 31622287 = 31622360
79 + 31622281 = 31622360
103 + 31622257 = 31622360
181 + 31622179 = 31622360
193 + 31622167 = 31622360
229 + 31622131 = 31622360

Showing the first eight; more decompositions exist.
