Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657520, here are decompositions:

7 + 8657513 = 8657520
17 + 8657503 = 8657520
59 + 8657461 = 8657520
71 + 8657449 = 8657520
89 + 8657431 = 8657520
97 + 8657423 = 8657520
139 + 8657381 = 8657520
163 + 8657357 = 8657520

Showing the first eight; more decompositions exist.
