Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185558, here are decompositions:

7 + 185551 = 185558
19 + 185539 = 185558
31 + 185527 = 185558
67 + 185491 = 185558
157 + 185401 = 185558
199 + 185359 = 185558
337 + 185221 = 185558
397 + 185161 = 185558

Showing the first eight; more decompositions exist.
