Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045372, here are decompositions:

5 + 1045367 = 1045372
23 + 1045349 = 1045372
131 + 1045241 = 1045372
149 + 1045223 = 1045372
173 + 1045199 = 1045372
179 + 1045193 = 1045372
311 + 1045061 = 1045372
359 + 1045013 = 1045372

Showing the first eight; more decompositions exist.
