Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742074, here are decompositions:

7 + 8742067 = 8742074
37 + 8742037 = 8742074
97 + 8741977 = 8742074
127 + 8741947 = 8742074
151 + 8741923 = 8742074
163 + 8741911 = 8742074
277 + 8741797 = 8742074
331 + 8741743 = 8742074

Showing the first eight; more decompositions exist.
