Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978836, here are decompositions:

37 + 978799 = 978836
109 + 978727 = 978836
139 + 978697 = 978836
193 + 978643 = 978836
373 + 978463 = 978836
379 + 978457 = 978836
409 + 978427 = 978836
433 + 978403 = 978836

Showing the first eight; more decompositions exist.
