Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752400, here are decompositions:

61 + 8752339 = 8752400
73 + 8752327 = 8752400
79 + 8752321 = 8752400
109 + 8752291 = 8752400
127 + 8752273 = 8752400
193 + 8752207 = 8752400
199 + 8752201 = 8752400
271 + 8752129 = 8752400

Showing the first eight; more decompositions exist.
