Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641162, here are decompositions:

29 + 8641133 = 8641162
83 + 8641079 = 8641162
251 + 8640911 = 8641162
401 + 8640761 = 8641162
443 + 8640719 = 8641162
449 + 8640713 = 8641162
461 + 8640701 = 8641162
479 + 8640683 = 8641162

Showing the first eight; more decompositions exist.
