Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83172, here are decompositions:
- 71 + 83101 = 83172
- 79 + 83093 = 83172
- 83 + 83089 = 83172
- 101 + 83071 = 83172
- 109 + 83063 = 83172
- 113 + 83059 = 83172
- 149 + 83023 = 83172
- 163 + 83009 = 83172
Showing the first eight; more decompositions exist.
