Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621552, here are decompositions:

61 + 8621491 = 8621552
73 + 8621479 = 8621552
109 + 8621443 = 8621552
139 + 8621413 = 8621552
271 + 8621281 = 8621552
409 + 8621143 = 8621552
463 + 8621089 = 8621552
601 + 8620951 = 8621552

Showing the first eight; more decompositions exist.
