Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931784, here are decompositions:

3 + 931781 = 931784
37 + 931747 = 931784
127 + 931657 = 931784
163 + 931621 = 931784
211 + 931573 = 931784
241 + 931543 = 931784
367 + 931417 = 931784
397 + 931387 = 931784

Showing the first eight; more decompositions exist.
