Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045660, here are decompositions:

17 + 1045643 = 1045660
53 + 1045607 = 1045660
89 + 1045571 = 1045660
101 + 1045559 = 1045660
113 + 1045547 = 1045660
131 + 1045529 = 1045660
137 + 1045523 = 1045660
167 + 1045493 = 1045660

Showing the first eight; more decompositions exist.
