Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641950, here are decompositions:

41 + 8641909 = 8641950
59 + 8641891 = 8641950
67 + 8641883 = 8641950
131 + 8641819 = 8641950
167 + 8641783 = 8641950
241 + 8641709 = 8641950
277 + 8641673 = 8641950
281 + 8641669 = 8641950

Showing the first eight; more decompositions exist.
