Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978132, here are decompositions:

19 + 978113 = 978132
41 + 978091 = 978132
53 + 978079 = 978132
59 + 978073 = 978132
61 + 978071 = 978132
79 + 978053 = 978132
83 + 978049 = 978132
101 + 978031 = 978132

Showing the first eight; more decompositions exist.
