Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 34640, here are decompositions:

37 + 34603 = 34640
97 + 34543 = 34640
103 + 34537 = 34640
127 + 34513 = 34640
139 + 34501 = 34640
157 + 34483 = 34640
211 + 34429 = 34640
271 + 34369 = 34640

Showing the first eight; more decompositions exist.
