Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004990, here are decompositions:

3 + 1004987 = 1004990
13 + 1004977 = 1004990
73 + 1004917 = 1004990
79 + 1004911 = 1004990
193 + 1004797 = 1004990
211 + 1004779 = 1004990
229 + 1004761 = 1004990
241 + 1004749 = 1004990

Showing the first eight; more decompositions exist.
