Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752120, here are decompositions:

53 + 8752067 = 8752120
89 + 8752031 = 8752120
233 + 8751887 = 8752120
257 + 8751863 = 8752120
281 + 8751839 = 8752120
317 + 8751803 = 8752120
347 + 8751773 = 8752120
353 + 8751767 = 8752120

Showing the first eight; more decompositions exist.
