Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648618, here are decompositions:

61 + 8648557 = 8648618
67 + 8648551 = 8648618
229 + 8648389 = 8648618
271 + 8648347 = 8648618
367 + 8648251 = 8648618
379 + 8648239 = 8648618
397 + 8648221 = 8648618
439 + 8648179 = 8648618

Showing the first eight; more decompositions exist.
