Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045772, here are decompositions:

43 + 1045729 = 1045772
109 + 1045663 = 1045772
139 + 1045633 = 1045772
151 + 1045621 = 1045772
199 + 1045573 = 1045772
223 + 1045549 = 1045772
229 + 1045543 = 1045772
349 + 1045423 = 1045772

Showing the first eight; more decompositions exist.
