Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659990, here are decompositions:

41 + 8659949 = 8659990
179 + 8659811 = 8659990
197 + 8659793 = 8659990
347 + 8659643 = 8659990
359 + 8659631 = 8659990
389 + 8659601 = 8659990
401 + 8659589 = 8659990
431 + 8659559 = 8659990

Showing the first eight; more decompositions exist.
