Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742268, here are decompositions:

5 + 8742263 = 8742268
71 + 8742197 = 8742268
107 + 8742161 = 8742268
191 + 8742077 = 8742268
257 + 8742011 = 8742268
281 + 8741987 = 8742268
317 + 8741951 = 8742268
401 + 8741867 = 8742268

Showing the first eight; more decompositions exist.
