Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045720, here are decompositions:

29 + 1045691 = 1045720
41 + 1045679 = 1045720
113 + 1045607 = 1045720
149 + 1045571 = 1045720
173 + 1045547 = 1045720
191 + 1045529 = 1045720
197 + 1045523 = 1045720
227 + 1045493 = 1045720

Showing the first eight; more decompositions exist.
