Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659580, here are decompositions:

37 + 8659543 = 8659580
43 + 8659537 = 8659580
67 + 8659513 = 8659580
79 + 8659501 = 8659580
109 + 8659471 = 8659580
157 + 8659423 = 8659580
199 + 8659381 = 8659580
229 + 8659351 = 8659580

Showing the first eight; more decompositions exist.
