Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020520, here are decompositions:

3 + 1020517 = 1020520
29 + 1020491 = 1020520
89 + 1020431 = 1020520
101 + 1020419 = 1020520
107 + 1020413 = 1020520
113 + 1020407 = 1020520
131 + 1020389 = 1020520
167 + 1020353 = 1020520

Showing the first eight; more decompositions exist.
