Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77912, here are decompositions:

13 + 77899 = 77912
19 + 77893 = 77912
73 + 77839 = 77912
139 + 77773 = 77912
151 + 77761 = 77912
181 + 77731 = 77912
193 + 77719 = 77912
199 + 77713 = 77912

Showing the first eight; more decompositions exist.
