Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979786, here are decompositions:

29 + 979757 = 979786
233 + 979553 = 979786
257 + 979529 = 979786
347 + 979439 = 979786
383 + 979403 = 979786
443 + 979343 = 979786
449 + 979337 = 979786
503 + 979283 = 979786

Showing the first eight; more decompositions exist.
