Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003666, here are decompositions:

47 + 1003619 = 1003666
149 + 1003517 = 1003666
197 + 1003469 = 1003666
233 + 1003433 = 1003666
269 + 1003397 = 1003666
317 + 1003349 = 1003666
359 + 1003307 = 1003666
467 + 1003199 = 1003666

Showing the first eight; more decompositions exist.
