Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71938, here are decompositions:
- 5 + 71933 = 71938
- 29 + 71909 = 71938
- 59 + 71879 = 71938
- 71 + 71867 = 71938
- 89 + 71849 = 71938
- 101 + 71837 = 71938
- 131 + 71807 = 71938
- 149 + 71789 = 71938
Showing the first eight; more decompositions exist.
