Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978084, here are decompositions:

5 + 978079 = 978084
7 + 978077 = 978084
11 + 978073 = 978084
13 + 978071 = 978084
17 + 978067 = 978084
31 + 978053 = 978084
43 + 978041 = 978084
47 + 978037 = 978084

Showing the first eight; more decompositions exist.
