Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026020, here are decompositions:

103 + 1025917 = 1026020
109 + 1025911 = 1026020
181 + 1025839 = 1026020
271 + 1025749 = 1026020
313 + 1025707 = 1026020
367 + 1025653 = 1026020
379 + 1025641 = 1026020
397 + 1025623 = 1026020

Showing the first eight; more decompositions exist.
