Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180248, here are decompositions:

7 + 180241 = 180248
37 + 180211 = 180248
67 + 180181 = 180248
151 + 180097 = 180248
241 + 180007 = 180248
331 + 179917 = 180248
349 + 179899 = 180248
421 + 179827 = 180248

Showing the first eight; more decompositions exist.
