Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659340, here are decompositions:

31 + 8659309 = 8659340
61 + 8659279 = 8659340
97 + 8659243 = 8659340
241 + 8659099 = 8659340
331 + 8659009 = 8659340
379 + 8658961 = 8659340
397 + 8658943 = 8659340
409 + 8658931 = 8659340

Showing the first eight; more decompositions exist.
