Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636874, here are decompositions:

5 + 8636869 = 8636874
17 + 8636857 = 8636874
73 + 8636801 = 8636874
83 + 8636791 = 8636874
137 + 8636737 = 8636874
173 + 8636701 = 8636874
227 + 8636647 = 8636874
241 + 8636633 = 8636874

Showing the first eight; more decompositions exist.
