Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649166, here are decompositions:

137 + 8649029 = 8649166
353 + 8648813 = 8649166
419 + 8648747 = 8649166
479 + 8648687 = 8649166
653 + 8648513 = 8649166
719 + 8648447 = 8649166
797 + 8648369 = 8649166
1187 + 8647979 = 8649166

Showing the first eight; more decompositions exist.
