Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727478, here are decompositions:

47 + 8727431 = 8727478
191 + 8727287 = 8727478
281 + 8727197 = 8727478
317 + 8727161 = 8727478
359 + 8727119 = 8727478
491 + 8726987 = 8727478
509 + 8726969 = 8727478
521 + 8726957 = 8727478

Showing the first eight; more decompositions exist.
