Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978020, here are decompositions:

3 + 978017 = 978020
13 + 978007 = 978020
19 + 978001 = 978020
97 + 977923 = 978020
139 + 977881 = 978020
229 + 977791 = 978020
349 + 977671 = 978020
409 + 977611 = 978020

Showing the first eight; more decompositions exist.
