Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98138, here are decompositions:
- 37 + 98101 = 98138
- 97 + 98041 = 98138
- 127 + 98011 = 98138
- 151 + 97987 = 98138
- 211 + 97927 = 98138
- 277 + 97861 = 98138
- 349 + 97789 = 98138
- 367 + 97771 = 98138
Showing the first eight; more decompositions exist.
