Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181352, here are decompositions:

79 + 181273 = 181352
109 + 181243 = 181352
139 + 181213 = 181352
151 + 181201 = 181352
211 + 181141 = 181352
229 + 181123 = 181352
271 + 181081 = 181352
313 + 181039 = 181352

Showing the first eight; more decompositions exist.
