Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979688, here are decompositions:

37 + 979651 = 979688
139 + 979549 = 979688
397 + 979291 = 979688
487 + 979201 = 979688
499 + 979189 = 979688
571 + 979117 = 979688
691 + 978997 = 979688
757 + 978931 = 979688

Showing the first eight; more decompositions exist.
