Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047140, here are decompositions:

7 + 1047133 = 1047140
13 + 1047127 = 1047140
43 + 1047097 = 1047140
79 + 1047061 = 1047140
97 + 1047043 = 1047140
109 + 1047031 = 1047140
163 + 1046977 = 1047140
181 + 1046959 = 1047140

Showing the first eight; more decompositions exist.
