Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172896, here are decompositions:
- 13 + 172883 = 172896
- 19 + 172877 = 172896
- 29 + 172867 = 172896
- 37 + 172859 = 172896
- 43 + 172853 = 172896
- 47 + 172849 = 172896
- 67 + 172829 = 172896
- 89 + 172807 = 172896
Showing the first eight; more decompositions exist.
