Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742544, here are decompositions:

3 + 8742541 = 8742544
47 + 8742497 = 8742544
191 + 8742353 = 8742544
197 + 8742347 = 8742544
227 + 8742317 = 8742544
281 + 8742263 = 8742544
347 + 8742197 = 8742544
383 + 8742161 = 8742544

Showing the first eight; more decompositions exist.
