Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707840, here are decompositions:

3 + 8707837 = 8707840
23 + 8707817 = 8707840
47 + 8707793 = 8707840
59 + 8707781 = 8707840
179 + 8707661 = 8707840
191 + 8707649 = 8707840
233 + 8707607 = 8707840
419 + 8707421 = 8707840

Showing the first eight; more decompositions exist.
