Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142886, here are decompositions:
- 13 + 142873 = 142886
- 19 + 142867 = 142886
- 97 + 142789 = 142886
- 127 + 142759 = 142886
- 229 + 142657 = 142886
- 277 + 142609 = 142886
- 313 + 142573 = 142886
- 349 + 142537 = 142886
Showing the first eight; more decompositions exist.
