Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742424, here are decompositions:

3 + 8742421 = 8742424
23 + 8742401 = 8742424
71 + 8742353 = 8742424
107 + 8742317 = 8742424
227 + 8742197 = 8742424
263 + 8742161 = 8742424
347 + 8742077 = 8742424
491 + 8741933 = 8742424

Showing the first eight; more decompositions exist.
