Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945072, here are decompositions:

13 + 945059 = 945072
41 + 945031 = 945072
103 + 944969 = 945072
109 + 944963 = 945072
173 + 944899 = 945072
179 + 944893 = 945072
199 + 944873 = 945072
239 + 944833 = 945072

Showing the first eight; more decompositions exist.
