Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979868, here are decompositions:

37 + 979831 = 979868
61 + 979807 = 979868
151 + 979717 = 979868
349 + 979519 = 979868
397 + 979471 = 979868
499 + 979369 = 979868
541 + 979327 = 979868
577 + 979291 = 979868

Showing the first eight; more decompositions exist.
