Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658438, here are decompositions:

7 + 8658431 = 8658438
67 + 8658371 = 8658438
109 + 8658329 = 8658438
149 + 8658289 = 8658438
277 + 8658161 = 8658438
331 + 8658107 = 8658438
337 + 8658101 = 8658438
379 + 8658059 = 8658438

Showing the first eight; more decompositions exist.
