Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75842, here are decompositions:
- 61 + 75781 = 75842
- 139 + 75703 = 75842
- 163 + 75679 = 75842
- 223 + 75619 = 75842
- 271 + 75571 = 75842
- 331 + 75511 = 75842
- 439 + 75403 = 75842
- 619 + 75223 = 75842
Showing the first eight; more decompositions exist.
