Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99978, here are decompositions:

7 + 99971 = 99978
17 + 99961 = 99978
71 + 99907 = 99978
97 + 99881 = 99978
101 + 99877 = 99978
107 + 99871 = 99978
139 + 99839 = 99978
149 + 99829 = 99978

Showing the first eight; more decompositions exist.
