Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649088, here are decompositions:

17 + 8649071 = 8649088
59 + 8649029 = 8649088
167 + 8648921 = 8649088
251 + 8648837 = 8649088
257 + 8648831 = 8649088
347 + 8648741 = 8649088
359 + 8648729 = 8649088
401 + 8648687 = 8649088

Showing the first eight; more decompositions exist.
