Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181274, here are decompositions:

31 + 181243 = 181274
61 + 181213 = 181274
73 + 181201 = 181274
151 + 181123 = 181274
193 + 181081 = 181274
211 + 181063 = 181274
271 + 181003 = 181274
367 + 180907 = 181274

Showing the first eight; more decompositions exist.
