Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622002, here are decompositions:

23 + 31621979 = 31622002
53 + 31621949 = 31622002
101 + 31621901 = 31622002
263 + 31621739 = 31622002
389 + 31621613 = 31622002
443 + 31621559 = 31622002
683 + 31621319 = 31622002
743 + 31621259 = 31622002

Showing the first eight; more decompositions exist.
