Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978226, here are decompositions:

3 + 978223 = 978226
17 + 978209 = 978226
23 + 978203 = 978226
47 + 978179 = 978226
113 + 978113 = 978226
149 + 978077 = 978226
173 + 978053 = 978226
479 + 977747 = 978226

Showing the first eight; more decompositions exist.
