Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931720, here are decompositions:

11 + 931709 = 931720
29 + 931691 = 931720
149 + 931571 = 931720
191 + 931529 = 931720
233 + 931487 = 931720
401 + 931319 = 931720
431 + 931289 = 931720
479 + 931241 = 931720

Showing the first eight; more decompositions exist.
