Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945128, here are decompositions:

97 + 945031 = 945128
199 + 944929 = 945128
229 + 944899 = 945128
241 + 944887 = 945128
271 + 944857 = 945128
307 + 944821 = 945128
397 + 944731 = 945128
439 + 944689 = 945128

Showing the first eight; more decompositions exist.
