Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931790, here are decompositions:

7 + 931783 = 931790
43 + 931747 = 931790
61 + 931729 = 931790
151 + 931639 = 931790
193 + 931597 = 931790
373 + 931417 = 931790
439 + 931351 = 931790
487 + 931303 = 931790

Showing the first eight; more decompositions exist.
