Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622984, here are decompositions:

37 + 31622947 = 31622984
61 + 31622923 = 31622984
103 + 31622881 = 31622984
181 + 31622803 = 31622984
241 + 31622743 = 31622984
271 + 31622713 = 31622984
313 + 31622671 = 31622984
607 + 31622377 = 31622984

Showing the first eight; more decompositions exist.
