Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978126, here are decompositions:

13 + 978113 = 978126
47 + 978079 = 978126
53 + 978073 = 978126
59 + 978067 = 978126
73 + 978053 = 978126
89 + 978037 = 978126
109 + 978017 = 978126
199 + 977927 = 978126

Showing the first eight; more decompositions exist.
