Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978130, here are decompositions:

17 + 978113 = 978130
53 + 978077 = 978130
59 + 978071 = 978130
89 + 978041 = 978130
113 + 978017 = 978130
233 + 977897 = 978130
269 + 977861 = 978130
281 + 977849 = 978130

Showing the first eight; more decompositions exist.
