Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20434, here are decompositions:

3 + 20431 = 20434
23 + 20411 = 20434
41 + 20393 = 20434
101 + 20333 = 20434
107 + 20327 = 20434
137 + 20297 = 20434
173 + 20261 = 20434
233 + 20201 = 20434

Showing the first eight; more decompositions exist.
