Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745340, here are decompositions:

11 + 8745329 = 8745340
29 + 8745311 = 8745340
41 + 8745299 = 8745340
101 + 8745239 = 8745340
113 + 8745227 = 8745340
137 + 8745203 = 8745340
179 + 8745161 = 8745340
239 + 8745101 = 8745340

Showing the first eight; more decompositions exist.
