Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001272, here are decompositions:

5 + 1001267 = 1001272
53 + 1001219 = 1001272
113 + 1001159 = 1001272
149 + 1001123 = 1001272
179 + 1001093 = 1001272
191 + 1001081 = 1001272
269 + 1001003 = 1001272
353 + 1000919 = 1001272

Showing the first eight; more decompositions exist.
