Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658524, here are decompositions:

31 + 8658493 = 8658524
211 + 8658313 = 8658524
307 + 8658217 = 8658524
331 + 8658193 = 8658524
421 + 8658103 = 8658524
541 + 8657983 = 8658524
601 + 8657923 = 8658524
643 + 8657881 = 8658524

Showing the first eight; more decompositions exist.
