Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752140, here are decompositions:

11 + 8752129 = 8752140
17 + 8752123 = 8752140
73 + 8752067 = 8752140
83 + 8752057 = 8752140
101 + 8752039 = 8752140
107 + 8752033 = 8752140
109 + 8752031 = 8752140
167 + 8751973 = 8752140

Showing the first eight; more decompositions exist.
