Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658402, here are decompositions:

19 + 8658383 = 8658402
31 + 8658371 = 8658402
73 + 8658329 = 8658402
79 + 8658323 = 8658402
89 + 8658313 = 8658402
113 + 8658289 = 8658402
199 + 8658203 = 8658402
241 + 8658161 = 8658402

Showing the first eight; more decompositions exist.
