Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001528, here are decompositions:

37 + 1001491 = 1001528
61 + 1001467 = 1001528
97 + 1001431 = 1001528
127 + 1001401 = 1001528
139 + 1001389 = 1001528
181 + 1001347 = 1001528
331 + 1001197 = 1001528
337 + 1001191 = 1001528

Showing the first eight; more decompositions exist.
