Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164558, here are decompositions:

109 + 164449 = 164558
127 + 164431 = 164558
139 + 164419 = 164558
181 + 164377 = 164558
307 + 164251 = 164558
349 + 164209 = 164558
367 + 164191 = 164558
409 + 164149 = 164558

Showing the first eight; more decompositions exist.
