Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39670, here are decompositions:
- 3 + 39667 = 39670
- 11 + 39659 = 39670
- 47 + 39623 = 39670
- 89 + 39581 = 39670
- 101 + 39569 = 39670
- 107 + 39563 = 39670
- 149 + 39521 = 39670
- 167 + 39503 = 39670
Showing the first eight; more decompositions exist.
