Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664520, here are decompositions:

3 + 8664517 = 8664520
47 + 8664473 = 8664520
89 + 8664431 = 8664520
101 + 8664419 = 8664520
107 + 8664413 = 8664520
131 + 8664389 = 8664520
191 + 8664329 = 8664520
467 + 8664053 = 8664520

Showing the first eight; more decompositions exist.
