Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84000, here are decompositions:
- 13 + 83987 = 84000
- 17 + 83983 = 84000
- 31 + 83969 = 84000
- 61 + 83939 = 84000
- 67 + 83933 = 84000
- 79 + 83921 = 84000
- 89 + 83911 = 84000
- 97 + 83903 = 84000
Showing the first eight; more decompositions exist.
