Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978580, here are decompositions:

11 + 978569 = 978580
59 + 978521 = 978580
89 + 978491 = 978580
101 + 978479 = 978580
107 + 978473 = 978580
131 + 978449 = 978580
167 + 978413 = 978580
191 + 978389 = 978580

Showing the first eight; more decompositions exist.
