Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001090, here are decompositions:

3 + 1001087 = 1001090
67 + 1001023 = 1001090
73 + 1001017 = 1001090
109 + 1000981 = 1001090
229 + 1000861 = 1001090
241 + 1000849 = 1001090
313 + 1000777 = 1001090
367 + 1000723 = 1001090

Showing the first eight; more decompositions exist.
