Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020478, here are decompositions:

47 + 1020431 = 1020478
59 + 1020419 = 1020478
71 + 1020407 = 1020478
89 + 1020389 = 1020478
149 + 1020329 = 1020478
401 + 1020077 = 1020478
419 + 1020059 = 1020478
467 + 1020011 = 1020478

Showing the first eight; more decompositions exist.
