Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736240, here are decompositions:

17 + 8736223 = 8736240
31 + 8736209 = 8736240
41 + 8736199 = 8736240
53 + 8736187 = 8736240
61 + 8736179 = 8736240
67 + 8736173 = 8736240
101 + 8736139 = 8736240
113 + 8736127 = 8736240

Showing the first eight; more decompositions exist.
