Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668340, here are decompositions:

61 + 8668279 = 8668340
67 + 8668273 = 8668340
73 + 8668267 = 8668340
139 + 8668201 = 8668340
199 + 8668141 = 8668340
229 + 8668111 = 8668340
277 + 8668063 = 8668340
283 + 8668057 = 8668340

Showing the first eight; more decompositions exist.
