Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40900, here are decompositions:
- 3 + 40897 = 40900
- 17 + 40883 = 40900
- 47 + 40853 = 40900
- 53 + 40847 = 40900
- 59 + 40841 = 40900
- 71 + 40829 = 40900
- 113 + 40787 = 40900
- 137 + 40763 = 40900
Showing the first eight; more decompositions exist.
