Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978146, here are decompositions:

67 + 978079 = 978146
73 + 978073 = 978146
79 + 978067 = 978146
97 + 978049 = 978146
109 + 978037 = 978146
139 + 978007 = 978146
223 + 977923 = 978146
607 + 977539 = 978146

Showing the first eight; more decompositions exist.
