Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005266, here are decompositions:

37 + 1005229 = 1005266
43 + 1005223 = 1005266
79 + 1005187 = 1005266
193 + 1005073 = 1005266
349 + 1004917 = 1005266
487 + 1004779 = 1005266
523 + 1004743 = 1005266
607 + 1004659 = 1005266

Showing the first eight; more decompositions exist.
