Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648738, here are decompositions:

37 + 8648701 = 8648738
61 + 8648677 = 8648738
181 + 8648557 = 8648738
349 + 8648389 = 8648738
367 + 8648371 = 8648738
421 + 8648317 = 8648738
487 + 8648251 = 8648738
499 + 8648239 = 8648738

Showing the first eight; more decompositions exist.
