Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991410, here are decompositions:

23 + 991387 = 991410
29 + 991381 = 991410
53 + 991357 = 991410
67 + 991343 = 991410
83 + 991327 = 991410
97 + 991313 = 991410
137 + 991273 = 991410
149 + 991261 = 991410

Showing the first eight; more decompositions exist.
