Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185354, here are decompositions:

31 + 185323 = 185354
193 + 185161 = 185354
223 + 185131 = 185354
277 + 185077 = 185354
283 + 185071 = 185354
397 + 184957 = 185354
523 + 184831 = 185354
577 + 184777 = 185354

Showing the first eight; more decompositions exist.
