Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72938, here are decompositions:
- 7 + 72931 = 72938
- 31 + 72907 = 72938
- 37 + 72901 = 72938
- 67 + 72871 = 72938
- 79 + 72859 = 72938
- 199 + 72739 = 72938
- 211 + 72727 = 72938
- 277 + 72661 = 72938
Showing the first eight; more decompositions exist.
