Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80902, here are decompositions:

5 + 80897 = 80902
53 + 80849 = 80902
71 + 80831 = 80902
83 + 80819 = 80902
113 + 80789 = 80902
233 + 80669 = 80902
251 + 80651 = 80902
281 + 80621 = 80902

Showing the first eight; more decompositions exist.
