Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80802, here are decompositions:

13 + 80789 = 80802
19 + 80783 = 80802
23 + 80779 = 80802
41 + 80761 = 80802
53 + 80749 = 80802
89 + 80713 = 80802
101 + 80701 = 80802
131 + 80671 = 80802

Showing the first eight; more decompositions exist.
