Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159772, here are decompositions:
- 3 + 159769 = 159772
- 71 + 159701 = 159772
- 89 + 159683 = 159772
- 101 + 159671 = 159772
- 149 + 159623 = 159772
- 233 + 159539 = 159772
- 251 + 159521 = 159772
- 269 + 159503 = 159772
Showing the first eight; more decompositions exist.
