Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78250, here are decompositions:
- 17 + 78233 = 78250
- 47 + 78203 = 78250
- 59 + 78191 = 78250
- 71 + 78179 = 78250
- 83 + 78167 = 78250
- 113 + 78137 = 78250
- 149 + 78101 = 78250
- 191 + 78059 = 78250
Showing the first eight; more decompositions exist.
