Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658378, here are decompositions:

7 + 8658371 = 8658378
89 + 8658289 = 8658378
101 + 8658277 = 8658378
241 + 8658137 = 8658378
269 + 8658109 = 8658378
271 + 8658107 = 8658378
277 + 8658101 = 8658378
409 + 8657969 = 8658378

Showing the first eight; more decompositions exist.
