Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978992, here are decompositions:

19 + 978973 = 978992
61 + 978931 = 978992
109 + 978883 = 978992
139 + 978853 = 978992
193 + 978799 = 978992
349 + 978643 = 978992
373 + 978619 = 978992
643 + 978349 = 978992

Showing the first eight; more decompositions exist.
