Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991554, here are decompositions:

7 + 991547 = 991554
13 + 991541 = 991554
23 + 991531 = 991554
43 + 991511 = 991554
61 + 991493 = 991554
71 + 991483 = 991554
101 + 991453 = 991554
107 + 991447 = 991554

Showing the first eight; more decompositions exist.
