Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978618, here are decompositions:

7 + 978611 = 978618
19 + 978599 = 978618
97 + 978521 = 978618
107 + 978511 = 978618
127 + 978491 = 978618
139 + 978479 = 978618
191 + 978427 = 978618
229 + 978389 = 978618

Showing the first eight; more decompositions exist.
