Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945372, here are decompositions:

5 + 945367 = 945372
13 + 945359 = 945372
23 + 945349 = 945372
31 + 945341 = 945372
41 + 945331 = 945372
79 + 945293 = 945372
83 + 945289 = 945372
139 + 945233 = 945372

Showing the first eight; more decompositions exist.
