Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145718, here are decompositions:
- 31 + 145687 = 145718
- 37 + 145681 = 145718
- 241 + 145477 = 145718
- 277 + 145441 = 145718
- 337 + 145381 = 145718
- 499 + 145219 = 145718
- 541 + 145177 = 145718
- 709 + 145009 = 145718
Showing the first eight; more decompositions exist.
