Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931904, here are decompositions:

3 + 931901 = 931904
31 + 931873 = 931904
67 + 931837 = 931904
157 + 931747 = 931904
283 + 931621 = 931904
307 + 931597 = 931904
331 + 931573 = 931904
367 + 931537 = 931904

Showing the first eight; more decompositions exist.
