Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978154, here are decompositions:

3 + 978151 = 978154
5 + 978149 = 978154
41 + 978113 = 978154
83 + 978071 = 978154
101 + 978053 = 978154
113 + 978041 = 978154
137 + 978017 = 978154
227 + 977927 = 978154

Showing the first eight; more decompositions exist.
