Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39898, here are decompositions:
- 11 + 39887 = 39898
- 29 + 39869 = 39898
- 41 + 39857 = 39898
- 59 + 39839 = 39898
- 71 + 39827 = 39898
- 107 + 39791 = 39898
- 137 + 39761 = 39898
- 149 + 39749 = 39898
Showing the first eight; more decompositions exist.
