Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81004, here are decompositions:

3 + 81001 = 81004
41 + 80963 = 81004
71 + 80933 = 81004
107 + 80897 = 81004
173 + 80831 = 81004
227 + 80777 = 81004
257 + 80747 = 81004
317 + 80687 = 81004

Showing the first eight; more decompositions exist.
