Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89404, here are decompositions:

5 + 89399 = 89404
11 + 89393 = 89404
17 + 89387 = 89404
23 + 89381 = 89404
41 + 89363 = 89404
101 + 89303 = 89404
131 + 89273 = 89404
167 + 89237 = 89404

Showing the first eight; more decompositions exist.
