Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77802, here are decompositions:

5 + 77797 = 77802
19 + 77783 = 77802
29 + 77773 = 77802
41 + 77761 = 77802
59 + 77743 = 77802
71 + 77731 = 77802
79 + 77723 = 77802
83 + 77719 = 77802

Showing the first eight; more decompositions exist.
