Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99742, here are decompositions:

23 + 99719 = 99742
29 + 99713 = 99742
53 + 99689 = 99742
131 + 99611 = 99742
179 + 99563 = 99742
191 + 99551 = 99742
311 + 99431 = 99742
491 + 99251 = 99742

Showing the first eight; more decompositions exist.
