Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020658, here are decompositions:

59 + 1020599 = 1020658
101 + 1020557 = 1020658
167 + 1020491 = 1020658
227 + 1020431 = 1020658
239 + 1020419 = 1020658
251 + 1020407 = 1020658
257 + 1020401 = 1020658
269 + 1020389 = 1020658

Showing the first eight; more decompositions exist.
