Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726140, here are decompositions:

47 + 8726093 = 8726140
53 + 8726087 = 8726140
89 + 8726051 = 8726140
113 + 8726027 = 8726140
149 + 8725991 = 8726140
179 + 8725961 = 8726140
191 + 8725949 = 8726140
263 + 8725877 = 8726140

Showing the first eight; more decompositions exist.
