Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648986, here are decompositions:

107 + 8648879 = 8648986
149 + 8648837 = 8648986
173 + 8648813 = 8648986
239 + 8648747 = 8648986
257 + 8648729 = 8648986
443 + 8648543 = 8648986
449 + 8648537 = 8648986
617 + 8648369 = 8648986

Showing the first eight; more decompositions exist.
