Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740472, here are decompositions:

19 + 8740453 = 8740472
43 + 8740429 = 8740472
61 + 8740411 = 8740472
79 + 8740393 = 8740472
151 + 8740321 = 8740472
199 + 8740273 = 8740472
571 + 8739901 = 8740472
661 + 8739811 = 8740472

Showing the first eight; more decompositions exist.
