Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84120, here are decompositions:
- 31 + 84089 = 84120
- 53 + 84067 = 84120
- 59 + 84061 = 84120
- 61 + 84059 = 84120
- 67 + 84053 = 84120
- 73 + 84047 = 84120
- 103 + 84017 = 84120
- 109 + 84011 = 84120
Showing the first eight; more decompositions exist.
