Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184978, here are decompositions:

11 + 184967 = 184978
29 + 184949 = 184978
149 + 184829 = 184978
251 + 184727 = 184978
257 + 184721 = 184978
347 + 184631 = 184978
401 + 184577 = 184978
419 + 184559 = 184978

Showing the first eight; more decompositions exist.
