Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931626, here are decompositions:

5 + 931621 = 931626
29 + 931597 = 931626
53 + 931573 = 931626
83 + 931543 = 931626
89 + 931537 = 931626
97 + 931529 = 931626
109 + 931517 = 931626
127 + 931499 = 931626

Showing the first eight; more decompositions exist.
