Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10840, here are decompositions:

3 + 10837 = 10840
41 + 10799 = 10840
59 + 10781 = 10840
101 + 10739 = 10840
107 + 10733 = 10840
131 + 10709 = 10840
149 + 10691 = 10840
173 + 10667 = 10840

Showing the first eight; more decompositions exist.
