Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621702, here are decompositions:

23 + 31621679 = 31621702
29 + 31621673 = 31621702
41 + 31621661 = 31621702
71 + 31621631 = 31621702
89 + 31621613 = 31621702
383 + 31621319 = 31621702
443 + 31621259 = 31621702
569 + 31621133 = 31621702

Showing the first eight; more decompositions exist.
