Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651520, here are decompositions:

13 + 8651507 = 8651520
19 + 8651501 = 8651520
61 + 8651459 = 8651520
83 + 8651437 = 8651520
131 + 8651389 = 8651520
167 + 8651353 = 8651520
191 + 8651329 = 8651520
197 + 8651323 = 8651520

Showing the first eight; more decompositions exist.
