Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19750, here are decompositions:

11 + 19739 = 19750
23 + 19727 = 19750
41 + 19709 = 19750
53 + 19697 = 19750
89 + 19661 = 19750
167 + 19583 = 19750
173 + 19577 = 19750
179 + 19571 = 19750

Showing the first eight; more decompositions exist.
