Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607520, here are decompositions:

41 + 8607479 = 8607520
71 + 8607449 = 8607520
107 + 8607413 = 8607520
113 + 8607407 = 8607520
137 + 8607383 = 8607520
149 + 8607371 = 8607520
179 + 8607341 = 8607520
191 + 8607329 = 8607520

Showing the first eight; more decompositions exist.
