Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945180, here are decompositions:

29 + 945151 = 945180
37 + 945143 = 945180
149 + 945031 = 945180
193 + 944987 = 945180
211 + 944969 = 945180
227 + 944953 = 945180
251 + 944929 = 945180
281 + 944899 = 945180

Showing the first eight; more decompositions exist.
