Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991544, here are decompositions:

3 + 991541 = 991544
13 + 991531 = 991544
61 + 991483 = 991544
97 + 991447 = 991544
157 + 991387 = 991544
163 + 991381 = 991544
271 + 991273 = 991544
283 + 991261 = 991544

Showing the first eight; more decompositions exist.
