Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736242, here are decompositions:

19 + 8736223 = 8736242
43 + 8736199 = 8736242
103 + 8736139 = 8736242
181 + 8736061 = 8736242
241 + 8736001 = 8736242
271 + 8735971 = 8736242
421 + 8735821 = 8736242
433 + 8735809 = 8736242

Showing the first eight; more decompositions exist.
