Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009930, here are decompositions:

3 + 1009927 = 1009930
29 + 1009901 = 1009930
71 + 1009859 = 1009930
149 + 1009781 = 1009930
281 + 1009649 = 1009930
293 + 1009637 = 1009930
431 + 1009499 = 1009930
443 + 1009487 = 1009930

Showing the first eight; more decompositions exist.
