Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978460, here are decompositions:

3 + 978457 = 978460
11 + 978449 = 978460
47 + 978413 = 978460
71 + 978389 = 978460
101 + 978359 = 978460
113 + 978347 = 978460
137 + 978323 = 978460
173 + 978287 = 978460

Showing the first eight; more decompositions exist.
