Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622784, here are decompositions:

5 + 31622779 = 31622784
7 + 31622777 = 31622784
41 + 31622743 = 31622784
43 + 31622741 = 31622784
71 + 31622713 = 31622784
97 + 31622687 = 31622784
101 + 31622683 = 31622784
113 + 31622671 = 31622784

Showing the first eight; more decompositions exist.
