Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39718, here are decompositions:
- 47 + 39671 = 39718
- 59 + 39659 = 39718
- 137 + 39581 = 39718
- 149 + 39569 = 39718
- 167 + 39551 = 39718
- 197 + 39521 = 39718
- 257 + 39461 = 39718
- 347 + 39371 = 39718
Showing the first eight; more decompositions exist.
