Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180308, here are decompositions:

19 + 180289 = 180308
61 + 180247 = 180308
67 + 180241 = 180308
97 + 180211 = 180308
127 + 180181 = 180308
211 + 180097 = 180308
307 + 180001 = 180308
409 + 179899 = 180308

Showing the first eight; more decompositions exist.
