Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978148, here are decompositions:

71 + 978077 = 978148
107 + 978041 = 978148
131 + 978017 = 978148
137 + 978011 = 978148
251 + 977897 = 978148
317 + 977831 = 978148
401 + 977747 = 978148
467 + 977681 = 978148

Showing the first eight; more decompositions exist.
