Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621634, here are decompositions:

3 + 31621631 = 31621634
13 + 31621621 = 31621634
43 + 31621591 = 31621634
73 + 31621561 = 31621634
103 + 31621531 = 31621634
127 + 31621507 = 31621634
157 + 31621477 = 31621634
193 + 31621441 = 31621634

Showing the first eight; more decompositions exist.
