Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021330, here are decompositions:

3 + 1021327 = 1021330
29 + 1021301 = 1021330
41 + 1021289 = 1021330
47 + 1021283 = 1021330
59 + 1021271 = 1021330
71 + 1021259 = 1021330
113 + 1021217 = 1021330
131 + 1021199 = 1021330

Showing the first eight; more decompositions exist.
