Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622006, here are decompositions:

43 + 31621963 = 31622006
109 + 31621897 = 31622006
127 + 31621879 = 31622006
313 + 31621693 = 31622006
337 + 31621669 = 31622006
373 + 31621633 = 31622006
499 + 31621507 = 31622006
607 + 31621399 = 31622006

Showing the first eight; more decompositions exist.
