Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756142, here are decompositions:

13 + 8756129 = 8756142
23 + 8756119 = 8756142
29 + 8756113 = 8756142
41 + 8756101 = 8756142
53 + 8756089 = 8756142
79 + 8756063 = 8756142
103 + 8756039 = 8756142
151 + 8755991 = 8756142

Showing the first eight; more decompositions exist.
