Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931778, here are decompositions:

31 + 931747 = 931778
139 + 931639 = 931778
157 + 931621 = 931778
181 + 931597 = 931778
241 + 931537 = 931778
541 + 931237 = 931778
691 + 931087 = 931778
787 + 930991 = 931778

Showing the first eight; more decompositions exist.
