Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143236, here are decompositions:
- 59 + 143177 = 143236
- 173 + 143063 = 143236
- 257 + 142979 = 143236
- 263 + 142973 = 143236
- 449 + 142787 = 143236
- 479 + 142757 = 143236
- 503 + 142733 = 143236
- 563 + 142673 = 143236
Showing the first eight; more decompositions exist.
