Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978192, here are decompositions:

11 + 978181 = 978192
13 + 978179 = 978192
41 + 978151 = 978192
43 + 978149 = 978192
79 + 978113 = 978192
101 + 978091 = 978192
113 + 978079 = 978192
139 + 978053 = 978192

Showing the first eight; more decompositions exist.
