Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83040, here are decompositions:
- 17 + 83023 = 83040
- 31 + 83009 = 83040
- 37 + 83003 = 83040
- 43 + 82997 = 83040
- 59 + 82981 = 83040
- 101 + 82939 = 83040
- 127 + 82913 = 83040
- 137 + 82903 = 83040
Showing the first eight; more decompositions exist.
