Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980128, here are decompositions:

11 + 980117 = 980128
47 + 980081 = 980128
59 + 980069 = 980128
101 + 980027 = 980128
179 + 979949 = 980128
239 + 979889 = 980128
419 + 979709 = 980128
587 + 979541 = 980128

Showing the first eight; more decompositions exist.
