Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80890, here are decompositions:

41 + 80849 = 80890
59 + 80831 = 80890
71 + 80819 = 80890
101 + 80789 = 80890
107 + 80783 = 80890
113 + 80777 = 80890
233 + 80657 = 80890
239 + 80651 = 80890

Showing the first eight; more decompositions exist.
