Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020454, here are decompositions:

3 + 1020451 = 1020454
23 + 1020431 = 1020454
41 + 1020413 = 1020454
47 + 1020407 = 1020454
53 + 1020401 = 1020454
101 + 1020353 = 1020454
311 + 1020143 = 1020454
317 + 1020137 = 1020454

Showing the first eight; more decompositions exist.
