Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40368, here are decompositions:
- 7 + 40361 = 40368
- 11 + 40357 = 40368
- 17 + 40351 = 40368
- 79 + 40289 = 40368
- 127 + 40241 = 40368
- 131 + 40237 = 40368
- 137 + 40231 = 40368
- 179 + 40189 = 40368
Showing the first eight; more decompositions exist.
