Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649132, here are decompositions:

29 + 8649103 = 8649132
53 + 8649079 = 8649132
61 + 8649071 = 8649132
71 + 8649061 = 8649132
83 + 8649049 = 8649132
103 + 8649029 = 8649132
109 + 8649023 = 8649132
131 + 8649001 = 8649132

Showing the first eight; more decompositions exist.
