Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40404, here are decompositions:
- 17 + 40387 = 40404
- 43 + 40361 = 40404
- 47 + 40357 = 40404
- 53 + 40351 = 40404
- 61 + 40343 = 40404
- 127 + 40277 = 40404
- 151 + 40253 = 40404
- 163 + 40241 = 40404
Showing the first eight; more decompositions exist.
