Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978090, here are decompositions:

11 + 978079 = 978090
13 + 978077 = 978090
17 + 978073 = 978090
19 + 978071 = 978090
23 + 978067 = 978090
37 + 978053 = 978090
41 + 978049 = 978090
53 + 978037 = 978090

Showing the first eight; more decompositions exist.
