Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980020, here are decompositions:

71 + 979949 = 980020
101 + 979919 = 980020
113 + 979907 = 980020
131 + 979889 = 980020
137 + 979883 = 980020
233 + 979787 = 980020
263 + 979757 = 980020
311 + 979709 = 980020

Showing the first eight; more decompositions exist.
