Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185398, here are decompositions:

29 + 185369 = 185398
71 + 185327 = 185398
89 + 185309 = 185398
107 + 185291 = 185398
131 + 185267 = 185398
347 + 185051 = 185398
401 + 184997 = 185398
431 + 184967 = 185398

Showing the first eight; more decompositions exist.
