Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979100, here are decompositions:

7 + 979093 = 979100
37 + 979063 = 979100
103 + 978997 = 979100
127 + 978973 = 979100
193 + 978907 = 979100
229 + 978871 = 979100
373 + 978727 = 979100
457 + 978643 = 979100

Showing the first eight; more decompositions exist.
