Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730240, here are decompositions:

11 + 8730229 = 8730240
59 + 8730181 = 8730240
83 + 8730157 = 8730240
89 + 8730151 = 8730240
137 + 8730103 = 8730240
149 + 8730091 = 8730240
157 + 8730083 = 8730240
163 + 8730077 = 8730240

Showing the first eight; more decompositions exist.
