Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024142, here are decompositions:

43 + 1024099 = 1024142
151 + 1023991 = 1024142
193 + 1023949 = 1024142
199 + 1023943 = 1024142
271 + 1023871 = 1024142
373 + 1023769 = 1024142
409 + 1023733 = 1024142
421 + 1023721 = 1024142

Showing the first eight; more decompositions exist.
