Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622102, here are decompositions:

139 + 31621963 = 31622102
223 + 31621879 = 31622102
271 + 31621831 = 31622102
349 + 31621753 = 31622102
409 + 31621693 = 31622102
433 + 31621669 = 31622102
541 + 31621561 = 31622102
571 + 31621531 = 31622102

Showing the first eight; more decompositions exist.
