Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047100, here are decompositions:

3 + 1047097 = 1047100
11 + 1047089 = 1047100
23 + 1047077 = 1047100
59 + 1047041 = 1047100
101 + 1046999 = 1047100
107 + 1046993 = 1047100
149 + 1046951 = 1047100
167 + 1046933 = 1047100

Showing the first eight; more decompositions exist.
