Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742274, here are decompositions:

11 + 8742263 = 8742274
113 + 8742161 = 8742274
197 + 8742077 = 8742274
263 + 8742011 = 8742274
461 + 8741813 = 8742274
521 + 8741753 = 8742274
587 + 8741687 = 8742274
881 + 8741393 = 8742274

Showing the first eight; more decompositions exist.
