Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757228, here are decompositions:

5 + 8757223 = 8757228
19 + 8757209 = 8757228
37 + 8757191 = 8757228
41 + 8757187 = 8757228
97 + 8757131 = 8757228
101 + 8757127 = 8757228
107 + 8757121 = 8757228
167 + 8757061 = 8757228

Showing the first eight; more decompositions exist.
