Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742008, here are decompositions:

19 + 8741989 = 8742008
31 + 8741977 = 8742008
61 + 8741947 = 8742008
97 + 8741911 = 8742008
211 + 8741797 = 8742008
229 + 8741779 = 8742008
367 + 8741641 = 8742008
487 + 8741521 = 8742008

Showing the first eight; more decompositions exist.
