Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759280, here are decompositions:

7 + 8759273 = 8759280
59 + 8759221 = 8759280
73 + 8759207 = 8759280
97 + 8759183 = 8759280
113 + 8759167 = 8759280
139 + 8759141 = 8759280
157 + 8759123 = 8759280
191 + 8759089 = 8759280

Showing the first eight; more decompositions exist.
