Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180452, here are decompositions:

61 + 180391 = 180452
73 + 180379 = 180452
163 + 180289 = 180452
193 + 180259 = 180452
211 + 180241 = 180452
241 + 180211 = 180452
271 + 180181 = 180452
379 + 180073 = 180452

Showing the first eight; more decompositions exist.
