Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029140, here are decompositions:

31 + 1029109 = 1029140
37 + 1029103 = 1029140
103 + 1029037 = 1029140
127 + 1029013 = 1029140
139 + 1029001 = 1029140
199 + 1028941 = 1029140
331 + 1028809 = 1029140
337 + 1028803 = 1029140

Showing the first eight; more decompositions exist.
