Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001242, here are decompositions:

5 + 1001237 = 1001242
23 + 1001219 = 1001242
83 + 1001159 = 1001242
89 + 1001153 = 1001242
149 + 1001093 = 1001242
173 + 1001069 = 1001242
239 + 1001003 = 1001242
269 + 1000973 = 1001242

Showing the first eight; more decompositions exist.
