Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980666, here are decompositions:

67 + 980599 = 980666
73 + 980593 = 980666
79 + 980587 = 980666
109 + 980557 = 980666
163 + 980503 = 980666
367 + 980299 = 980666
373 + 980293 = 980666
487 + 980179 = 980666

Showing the first eight; more decompositions exist.
