Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649148, here are decompositions:

227 + 8648921 = 8649148
269 + 8648879 = 8649148
281 + 8648867 = 8649148
311 + 8648837 = 8649148
317 + 8648831 = 8649148
401 + 8648747 = 8649148
419 + 8648729 = 8649148
461 + 8648687 = 8649148

Showing the first eight; more decompositions exist.
