Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978290, here are decompositions:

3 + 978287 = 978290
7 + 978283 = 978290
13 + 978277 = 978290
67 + 978223 = 978290
73 + 978217 = 978290
109 + 978181 = 978290
139 + 978151 = 978290
199 + 978091 = 978290

Showing the first eight; more decompositions exist.
