Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622342, here are decompositions:

61 + 31622281 = 31622342
163 + 31622179 = 31622342
211 + 31622131 = 31622342
223 + 31622119 = 31622342
229 + 31622113 = 31622342
379 + 31621963 = 31622342
463 + 31621879 = 31622342
673 + 31621669 = 31622342

Showing the first eight; more decompositions exist.
