Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65458, here are decompositions:

11 + 65447 = 65458
101 + 65357 = 65458
131 + 65327 = 65458
149 + 65309 = 65458
191 + 65267 = 65458
311 + 65147 = 65458
317 + 65141 = 65458
347 + 65111 = 65458

Showing the first eight; more decompositions exist.
