Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40912, here are decompositions:
- 29 + 40883 = 40912
- 59 + 40853 = 40912
- 71 + 40841 = 40912
- 83 + 40829 = 40912
- 89 + 40823 = 40912
- 149 + 40763 = 40912
- 173 + 40739 = 40912
- 353 + 40559 = 40912
Showing the first eight; more decompositions exist.
