Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745528, here are decompositions:

5 + 8745523 = 8745528
79 + 8745449 = 8745528
109 + 8745419 = 8745528
199 + 8745329 = 8745528
229 + 8745299 = 8745528
359 + 8745169 = 8745528
367 + 8745161 = 8745528
409 + 8745119 = 8745528

Showing the first eight; more decompositions exist.
