Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648436, here are decompositions:

23 + 8648413 = 8648436
47 + 8648389 = 8648436
67 + 8648369 = 8648436
89 + 8648347 = 8648436
103 + 8648333 = 8648436
113 + 8648323 = 8648436
197 + 8648239 = 8648436
257 + 8648179 = 8648436

Showing the first eight; more decompositions exist.
