Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637554, here are decompositions:

31 + 8637523 = 8637554
61 + 8637493 = 8637554
73 + 8637481 = 8637554
103 + 8637451 = 8637554
127 + 8637427 = 8637554
181 + 8637373 = 8637554
307 + 8637247 = 8637554
421 + 8637133 = 8637554

Showing the first eight; more decompositions exist.
