Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730440, here are decompositions:

97 + 8730343 = 8730440
109 + 8730331 = 8730440
157 + 8730283 = 8730440
211 + 8730229 = 8730440
283 + 8730157 = 8730440
337 + 8730103 = 8730440
349 + 8730091 = 8730440
373 + 8730067 = 8730440

Showing the first eight; more decompositions exist.
