Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688142, here are decompositions:

41 + 8688101 = 8688142
59 + 8688083 = 8688142
83 + 8688059 = 8688142
131 + 8688011 = 8688142
149 + 8687993 = 8688142
179 + 8687963 = 8688142
251 + 8687891 = 8688142
263 + 8687879 = 8688142

Showing the first eight; more decompositions exist.
