Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84100, here are decompositions:
- 11 + 84089 = 84100
- 41 + 84059 = 84100
- 47 + 84053 = 84100
- 53 + 84047 = 84100
- 83 + 84017 = 84100
- 89 + 84011 = 84100
- 113 + 83987 = 84100
- 131 + 83969 = 84100
Showing the first eight; more decompositions exist.
