Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742674, here are decompositions:

37 + 8742637 = 8742674
97 + 8742577 = 8742674
103 + 8742571 = 8742674
163 + 8742511 = 8742674
181 + 8742493 = 8742674
211 + 8742463 = 8742674
307 + 8742367 = 8742674
487 + 8742187 = 8742674

Showing the first eight; more decompositions exist.
