Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180270, here are decompositions:

7 + 180263 = 180270
11 + 180259 = 180270
23 + 180247 = 180270
29 + 180241 = 180270
31 + 180239 = 180270
37 + 180233 = 180270
59 + 180211 = 180270
89 + 180181 = 180270

Showing the first eight; more decompositions exist.
