Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40920, here are decompositions:
- 17 + 40903 = 40920
- 23 + 40897 = 40920
- 37 + 40883 = 40920
- 41 + 40879 = 40920
- 53 + 40867 = 40920
- 67 + 40853 = 40920
- 71 + 40849 = 40920
- 73 + 40847 = 40920
Showing the first eight; more decompositions exist.
