Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023900, here are decompositions:

29 + 1023871 = 1023900
43 + 1023857 = 1023900
61 + 1023839 = 1023900
67 + 1023833 = 1023900
79 + 1023821 = 1023900
131 + 1023769 = 1023900
149 + 1023751 = 1023900
167 + 1023733 = 1023900

Showing the first eight; more decompositions exist.
