Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931686, here are decompositions:

29 + 931657 = 931686
47 + 931639 = 931686
89 + 931597 = 931686
109 + 931577 = 931686
113 + 931573 = 931686
149 + 931537 = 931686
157 + 931529 = 931686
199 + 931487 = 931686

Showing the first eight; more decompositions exist.
