Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978612, here are decompositions:

13 + 978599 = 978612
43 + 978569 = 978612
71 + 978541 = 978612
101 + 978511 = 978612
139 + 978473 = 978612
149 + 978463 = 978612
163 + 978449 = 978612
199 + 978413 = 978612

Showing the first eight; more decompositions exist.
