Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662580, here are decompositions:

97 + 8662483 = 8662580
109 + 8662471 = 8662580
127 + 8662453 = 8662580
139 + 8662441 = 8662580
307 + 8662273 = 8662580
331 + 8662249 = 8662580
337 + 8662243 = 8662580
379 + 8662201 = 8662580

Showing the first eight; more decompositions exist.
