Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704520, here are decompositions:

7 + 8704513 = 8704520
103 + 8704417 = 8704520
151 + 8704369 = 8704520
211 + 8704309 = 8704520
241 + 8704279 = 8704520
337 + 8704183 = 8704520
397 + 8704123 = 8704520
577 + 8703943 = 8704520

Showing the first eight; more decompositions exist.
