Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978190, here are decompositions:

11 + 978179 = 978190
41 + 978149 = 978190
113 + 978077 = 978190
137 + 978053 = 978190
149 + 978041 = 978190
173 + 978017 = 978190
179 + 978011 = 978190
263 + 977927 = 978190

Showing the first eight; more decompositions exist.
