Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726130, here are decompositions:

29 + 8726101 = 8726130
37 + 8726093 = 8726130
43 + 8726087 = 8726130
67 + 8726063 = 8726130
79 + 8726051 = 8726130
103 + 8726027 = 8726130
109 + 8726021 = 8726130
113 + 8726017 = 8726130

Showing the first eight; more decompositions exist.
