Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649274, here are decompositions:

47 + 8649227 = 8649274
83 + 8649191 = 8649274
251 + 8649023 = 8649274
353 + 8648921 = 8649274
443 + 8648831 = 8649274
461 + 8648813 = 8649274
587 + 8648687 = 8649274
743 + 8648531 = 8649274

Showing the first eight; more decompositions exist.
