Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21914, here are decompositions:

3 + 21911 = 21914
43 + 21871 = 21914
73 + 21841 = 21914
97 + 21817 = 21914
127 + 21787 = 21914
157 + 21757 = 21914
163 + 21751 = 21914
241 + 21673 = 21914

Showing the first eight; more decompositions exist.
