Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752240, here are decompositions:

53 + 8752187 = 8752240
59 + 8752181 = 8752240
83 + 8752157 = 8752240
173 + 8752067 = 8752240
353 + 8751887 = 8752240
401 + 8751839 = 8752240
467 + 8751773 = 8752240
491 + 8751749 = 8752240

Showing the first eight; more decompositions exist.
