Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78938, here are decompositions:
- 19 + 78919 = 78938
- 37 + 78901 = 78938
- 61 + 78877 = 78938
- 151 + 78787 = 78938
- 157 + 78781 = 78938
- 241 + 78697 = 78938
- 331 + 78607 = 78938
- 367 + 78571 = 78938
Showing the first eight; more decompositions exist.
