Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84154, here are decompositions:
- 11 + 84143 = 84154
- 17 + 84137 = 84154
- 23 + 84131 = 84154
- 101 + 84053 = 84154
- 107 + 84047 = 84154
- 137 + 84017 = 84154
- 167 + 83987 = 84154
- 233 + 83921 = 84154
Showing the first eight; more decompositions exist.
