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.
