Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 929840, here are decompositions:

31 + 929809 = 929840
97 + 929743 = 929840
103 + 929737 = 929840
193 + 929647 = 929840
199 + 929641 = 929840
211 + 929629 = 929840
283 + 929557 = 929840
313 + 929527 = 929840

Showing the first eight; more decompositions exist.
