Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023172, here are decompositions:

5 + 1023167 = 1023172
71 + 1023101 = 1023172
89 + 1023083 = 1023172
131 + 1023041 = 1023172
191 + 1022981 = 1023172
239 + 1022933 = 1023172
281 + 1022891 = 1023172
443 + 1022729 = 1023172

Showing the first eight; more decompositions exist.
