Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752500, here are decompositions:

23 + 8752477 = 8752500
59 + 8752441 = 8752500
73 + 8752427 = 8752500
79 + 8752421 = 8752500
83 + 8752417 = 8752500
139 + 8752361 = 8752500
173 + 8752327 = 8752500
179 + 8752321 = 8752500

Showing the first eight; more decompositions exist.
