Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023100, here are decompositions:

17 + 1023083 = 1023100
53 + 1023047 = 1023100
59 + 1023041 = 1023100
137 + 1022963 = 1023100
167 + 1022933 = 1023100
251 + 1022849 = 1023100
257 + 1022843 = 1023100
263 + 1022837 = 1023100

Showing the first eight; more decompositions exist.
