Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047320, here are decompositions:

3 + 1047317 = 1047320
7 + 1047313 = 1047320
13 + 1047307 = 1047320
31 + 1047289 = 1047320
37 + 1047283 = 1047320
73 + 1047247 = 1047320
163 + 1047157 = 1047320
181 + 1047139 = 1047320

Showing the first eight; more decompositions exist.
