Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622042, here are decompositions:

61 + 31621981 = 31622042
79 + 31621963 = 31622042
163 + 31621879 = 31622042
211 + 31621831 = 31622042
349 + 31621693 = 31622042
373 + 31621669 = 31622042
409 + 31621633 = 31622042
421 + 31621621 = 31622042

Showing the first eight; more decompositions exist.
