Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978078, here are decompositions:

5 + 978073 = 978078
7 + 978071 = 978078
11 + 978067 = 978078
29 + 978049 = 978078
37 + 978041 = 978078
41 + 978037 = 978078
47 + 978031 = 978078
61 + 978017 = 978078

Showing the first eight; more decompositions exist.
