Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978174, here are decompositions:

17 + 978157 = 978174
23 + 978151 = 978174
61 + 978113 = 978174
83 + 978091 = 978174
97 + 978077 = 978174
101 + 978073 = 978174
103 + 978071 = 978174
107 + 978067 = 978174

Showing the first eight; more decompositions exist.
