Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84040, here are decompositions:
- 23 + 84017 = 84040
- 29 + 84011 = 84040
- 53 + 83987 = 84040
- 71 + 83969 = 84040
- 101 + 83939 = 84040
- 107 + 83933 = 84040
- 137 + 83903 = 84040
- 149 + 83891 = 84040
Showing the first eight; more decompositions exist.
