Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978206, here are decompositions:

3 + 978203 = 978206
127 + 978079 = 978206
139 + 978067 = 978206
157 + 978049 = 978206
199 + 978007 = 978206
283 + 977923 = 978206
487 + 977719 = 978206
577 + 977629 = 978206

Showing the first eight; more decompositions exist.
