Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39700, here are decompositions:
- 29 + 39671 = 39700
- 41 + 39659 = 39700
- 131 + 39569 = 39700
- 137 + 39563 = 39700
- 149 + 39551 = 39700
- 179 + 39521 = 39700
- 191 + 39509 = 39700
- 197 + 39503 = 39700
Showing the first eight; more decompositions exist.
