Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979642, here are decompositions:

89 + 979553 = 979642
101 + 979541 = 979642
113 + 979529 = 979642
239 + 979403 = 979642
263 + 979379 = 979642
269 + 979373 = 979642
281 + 979361 = 979642
359 + 979283 = 979642

Showing the first eight; more decompositions exist.
