Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045678, here are decompositions:

71 + 1045607 = 1045678
107 + 1045571 = 1045678
131 + 1045547 = 1045678
149 + 1045529 = 1045678
191 + 1045487 = 1045678
251 + 1045427 = 1045678
269 + 1045409 = 1045678
281 + 1045397 = 1045678

Showing the first eight; more decompositions exist.
