Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658506, here are decompositions:

13 + 8658493 = 8658506
37 + 8658469 = 8658506
193 + 8658313 = 8658506
229 + 8658277 = 8658506
313 + 8658193 = 8658506
397 + 8658109 = 8658506
463 + 8658043 = 8658506
523 + 8657983 = 8658506

Showing the first eight; more decompositions exist.
