Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77870, here are decompositions:

3 + 77867 = 77870
7 + 77863 = 77870
31 + 77839 = 77870
73 + 77797 = 77870
97 + 77773 = 77870
109 + 77761 = 77870
127 + 77743 = 77870
139 + 77731 = 77870

Showing the first eight; more decompositions exist.
