Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021082, here are decompositions:

103 + 1020979 = 1021082
109 + 1020973 = 1021082
151 + 1020931 = 1021082
229 + 1020853 = 1021082
241 + 1020841 = 1021082
331 + 1020751 = 1021082
373 + 1020709 = 1021082
463 + 1020619 = 1021082

Showing the first eight; more decompositions exist.
