Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20012, here are decompositions:

19 + 19993 = 20012
151 + 19861 = 20012
193 + 19819 = 20012
199 + 19813 = 20012
211 + 19801 = 20012
313 + 19699 = 20012
331 + 19681 = 20012
409 + 19603 = 20012

Showing the first eight; more decompositions exist.
