Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978086, here are decompositions:

7 + 978079 = 978086
13 + 978073 = 978086
19 + 978067 = 978086
37 + 978049 = 978086
79 + 978007 = 978086
163 + 977923 = 978086
283 + 977803 = 978086
367 + 977719 = 978086

Showing the first eight; more decompositions exist.
