Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732278, here are decompositions:

17 + 8732261 = 8732278
89 + 8732189 = 8732278
197 + 8732081 = 8732278
227 + 8732051 = 8732278
251 + 8732027 = 8732278
419 + 8731859 = 8732278
461 + 8731817 = 8732278
491 + 8731787 = 8732278

Showing the first eight; more decompositions exist.
