Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180212, here are decompositions:

31 + 180181 = 180212
139 + 180073 = 180212
211 + 180001 = 180212
223 + 179989 = 180212
313 + 179899 = 180212
379 + 179833 = 180212
433 + 179779 = 180212
463 + 179749 = 180212

Showing the first eight; more decompositions exist.
