Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10012, here are decompositions:

3 + 10009 = 10012
5 + 10007 = 10012
71 + 9941 = 10012
83 + 9929 = 10012
89 + 9923 = 10012
173 + 9839 = 10012
179 + 9833 = 10012
263 + 9749 = 10012

Showing the first eight; more decompositions exist.
