Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181348, here are decompositions:

47 + 181301 = 181348
71 + 181277 = 181348
137 + 181211 = 181348
149 + 181199 = 181348
191 + 181157 = 181348
317 + 181031 = 181348
347 + 181001 = 181348
389 + 180959 = 181348

Showing the first eight; more decompositions exist.
