Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143864, here are decompositions:
- 31 + 143833 = 143864
- 37 + 143827 = 143864
- 43 + 143821 = 143864
- 67 + 143797 = 143864
- 73 + 143791 = 143864
- 211 + 143653 = 143864
- 271 + 143593 = 143864
- 313 + 143551 = 143864
Showing the first eight; more decompositions exist.
