Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040372, here are decompositions:

19 + 1040353 = 1040372
61 + 1040311 = 1040372
181 + 1040191 = 1040372
211 + 1040161 = 1040372
271 + 1040101 = 1040372
283 + 1040089 = 1040372
313 + 1040059 = 1040372
373 + 1039999 = 1040372

Showing the first eight; more decompositions exist.
