Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619966, here are decompositions:

23 + 8619943 = 8619966
29 + 8619937 = 8619966
73 + 8619893 = 8619966
83 + 8619883 = 8619966
97 + 8619869 = 8619966
107 + 8619859 = 8619966
109 + 8619857 = 8619966
149 + 8619817 = 8619966

Showing the first eight; more decompositions exist.
