Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115938, here are decompositions:
- 5 + 115933 = 115938
- 7 + 115931 = 115938
- 37 + 115901 = 115938
- 47 + 115891 = 115938
- 59 + 115879 = 115938
- 61 + 115877 = 115938
- 79 + 115859 = 115938
- 89 + 115849 = 115938
Showing the first eight; more decompositions exist.
