Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045888, here are decompositions:

29 + 1045859 = 1045888
47 + 1045841 = 1045888
59 + 1045829 = 1045888
89 + 1045799 = 1045888
149 + 1045739 = 1045888
197 + 1045691 = 1045888
281 + 1045607 = 1045888
317 + 1045571 = 1045888

Showing the first eight; more decompositions exist.
