Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746520, here are decompositions:

7 + 8746513 = 8746520
61 + 8746459 = 8746520
67 + 8746453 = 8746520
73 + 8746447 = 8746520
151 + 8746369 = 8746520
163 + 8746357 = 8746520
283 + 8746237 = 8746520
313 + 8746207 = 8746520

Showing the first eight; more decompositions exist.
