Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978080, here are decompositions:

3 + 978077 = 978080
7 + 978073 = 978080
13 + 978067 = 978080
31 + 978049 = 978080
43 + 978037 = 978080
73 + 978007 = 978080
79 + 978001 = 978080
109 + 977971 = 978080

Showing the first eight; more decompositions exist.
