Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979666, here are decompositions:

113 + 979553 = 979666
137 + 979529 = 979666
227 + 979439 = 979666
263 + 979403 = 979666
293 + 979373 = 979666
353 + 979313 = 979666
383 + 979283 = 979666
503 + 979163 = 979666

Showing the first eight; more decompositions exist.
