Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21134, here are decompositions:

13 + 21121 = 21134
67 + 21067 = 21134
73 + 21061 = 21134
103 + 21031 = 21134
151 + 20983 = 21134
277 + 20857 = 21134
523 + 20611 = 21134
541 + 20593 = 21134

Showing the first eight; more decompositions exist.
