Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745480, here are decompositions:

31 + 8745449 = 8745480
43 + 8745437 = 8745480
61 + 8745419 = 8745480
113 + 8745367 = 8745480
127 + 8745353 = 8745480
137 + 8745343 = 8745480
151 + 8745329 = 8745480
173 + 8745307 = 8745480

Showing the first eight; more decompositions exist.
