Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736228, here are decompositions:

5 + 8736223 = 8736228
19 + 8736209 = 8736228
29 + 8736199 = 8736228
37 + 8736191 = 8736228
41 + 8736187 = 8736228
89 + 8736139 = 8736228
101 + 8736127 = 8736228
131 + 8736097 = 8736228

Showing the first eight; more decompositions exist.
