Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184858, here are decompositions:

29 + 184829 = 184858
131 + 184727 = 184858
137 + 184721 = 184858
227 + 184631 = 184858
251 + 184607 = 184858
281 + 184577 = 184858
347 + 184511 = 184858
449 + 184409 = 184858

Showing the first eight; more decompositions exist.
