Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39998, here are decompositions:
- 19 + 39979 = 39998
- 61 + 39937 = 39998
- 97 + 39901 = 39998
- 151 + 39847 = 39998
- 157 + 39841 = 39998
- 199 + 39799 = 39998
- 229 + 39769 = 39998
- 271 + 39727 = 39998
Showing the first eight; more decompositions exist.
