Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99972, here are decompositions:

11 + 99961 = 99972
43 + 99929 = 99972
71 + 99901 = 99972
101 + 99871 = 99972
113 + 99859 = 99972
139 + 99833 = 99972
149 + 99823 = 99972
163 + 99809 = 99972

Showing the first eight; more decompositions exist.
