Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 535840, here are decompositions:

29 + 535811 = 535840
47 + 535793 = 535840
83 + 535757 = 535840
89 + 535751 = 535840
113 + 535727 = 535840
131 + 535709 = 535840
167 + 535673 = 535840
233 + 535607 = 535840

Showing the first eight; more decompositions exist.
