Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978074, here are decompositions:

3 + 978071 = 978074
7 + 978067 = 978074
37 + 978037 = 978074
43 + 978031 = 978074
67 + 978007 = 978074
73 + 978001 = 978074
103 + 977971 = 978074
151 + 977923 = 978074

Showing the first eight; more decompositions exist.
