Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028830, here are decompositions:

53 + 1028777 = 1028830
83 + 1028747 = 1028830
149 + 1028681 = 1028830
167 + 1028663 = 1028830
233 + 1028597 = 1028830
251 + 1028579 = 1028830
269 + 1028561 = 1028830
359 + 1028471 = 1028830

Showing the first eight; more decompositions exist.
