Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77990, here are decompositions:

7 + 77983 = 77990
13 + 77977 = 77990
61 + 77929 = 77990
97 + 77893 = 77990
127 + 77863 = 77990
151 + 77839 = 77990
193 + 77797 = 77990
229 + 77761 = 77990

Showing the first eight; more decompositions exist.
