Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81064, here are decompositions:

17 + 81047 = 81064
23 + 81041 = 81064
41 + 81023 = 81064
47 + 81017 = 81064
101 + 80963 = 81064
131 + 80933 = 81064
167 + 80897 = 81064
233 + 80831 = 81064

Showing the first eight; more decompositions exist.
