Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635840, here are decompositions:

23 + 8635817 = 8635840
29 + 8635811 = 8635840
167 + 8635673 = 8635840
173 + 8635667 = 8635840
233 + 8635607 = 8635840
281 + 8635559 = 8635840
431 + 8635409 = 8635840
557 + 8635283 = 8635840

Showing the first eight; more decompositions exist.
