Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931840, here are decompositions:

3 + 931837 = 931840
29 + 931811 = 931840
59 + 931781 = 931840
83 + 931757 = 931840
89 + 931751 = 931840
101 + 931739 = 931840
113 + 931727 = 931840
131 + 931709 = 931840

Showing the first eight; more decompositions exist.
