Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931668, here are decompositions:

11 + 931657 = 931668
29 + 931639 = 931668
47 + 931621 = 931668
71 + 931597 = 931668
97 + 931571 = 931668
131 + 931537 = 931668
139 + 931529 = 931668
151 + 931517 = 931668

Showing the first eight; more decompositions exist.
