Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162340, here are decompositions:

47 + 162293 = 162340
53 + 162287 = 162340
71 + 162269 = 162340
83 + 162257 = 162340
89 + 162251 = 162340
131 + 162209 = 162340
197 + 162143 = 162340
281 + 162059 = 162340

Showing the first eight; more decompositions exist.
