Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945240, here are decompositions:

7 + 945233 = 945240
13 + 945227 = 945240
29 + 945211 = 945240
31 + 945209 = 945240
61 + 945179 = 945240
89 + 945151 = 945240
97 + 945143 = 945240
137 + 945103 = 945240

Showing the first eight; more decompositions exist.
