Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999542, here are decompositions:

13 + 999529 = 999542
43 + 999499 = 999542
109 + 999433 = 999542
211 + 999331 = 999542
373 + 999169 = 999542
409 + 999133 = 999542
499 + 999043 = 999542
601 + 998941 = 999542

Showing the first eight; more decompositions exist.
