Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757144, here are decompositions:

13 + 8757131 = 8757144
17 + 8757127 = 8757144
23 + 8757121 = 8757144
31 + 8757113 = 8757144
37 + 8757107 = 8757144
61 + 8757083 = 8757144
83 + 8757061 = 8757144
103 + 8757041 = 8757144

Showing the first eight; more decompositions exist.
