Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143226, here are decompositions:

29 + 143197 = 143226
67 + 143159 = 143226
89 + 143137 = 143226
113 + 143113 = 143226
163 + 143063 = 143226
173 + 143053 = 143226
233 + 142993 = 143226
257 + 142969 = 143226

Showing the first eight; more decompositions exist.
