Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84172, here are decompositions:
- 29 + 84143 = 84172
- 41 + 84131 = 84172
- 83 + 84089 = 84172
- 113 + 84059 = 84172
- 233 + 83939 = 84172
- 239 + 83933 = 84172
- 251 + 83921 = 84172
- 269 + 83903 = 84172
Showing the first eight; more decompositions exist.
