Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020372, here are decompositions:

11 + 1020361 = 1020372
19 + 1020353 = 1020372
43 + 1020329 = 1020372
71 + 1020301 = 1020372
79 + 1020293 = 1020372
103 + 1020269 = 1020372
113 + 1020259 = 1020372
139 + 1020233 = 1020372

Showing the first eight; more decompositions exist.
