Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742548, here are decompositions:

7 + 8742541 = 8742548
19 + 8742529 = 8742548
37 + 8742511 = 8742548
79 + 8742469 = 8742548
127 + 8742421 = 8742548
181 + 8742367 = 8742548
379 + 8742169 = 8742548
571 + 8741977 = 8742548

Showing the first eight; more decompositions exist.
