Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002172, here are decompositions:

23 + 1002149 = 1002172
29 + 1002143 = 1002172
71 + 1002101 = 1002172
89 + 1002083 = 1002172
191 + 1001981 = 1002172
239 + 1001933 = 1002172
389 + 1001783 = 1002172
449 + 1001723 = 1002172

Showing the first eight; more decompositions exist.
