Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979870, here are decompositions:

83 + 979787 = 979870
113 + 979757 = 979870
179 + 979691 = 979870
317 + 979553 = 979870
389 + 979481 = 979870
431 + 979439 = 979870
467 + 979403 = 979870
491 + 979379 = 979870

Showing the first eight; more decompositions exist.
