Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658412, here are decompositions:

29 + 8658383 = 8658412
41 + 8658371 = 8658412
83 + 8658329 = 8658412
89 + 8658323 = 8658412
179 + 8658233 = 8658412
251 + 8658161 = 8658412
311 + 8658101 = 8658412
353 + 8658059 = 8658412

Showing the first eight; more decompositions exist.
