Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39938, here are decompositions:
- 37 + 39901 = 39938
- 61 + 39877 = 39938
- 97 + 39841 = 39938
- 109 + 39829 = 39938
- 139 + 39799 = 39938
- 211 + 39727 = 39938
- 229 + 39709 = 39938
- 271 + 39667 = 39938
Showing the first eight; more decompositions exist.
