Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78288, here are decompositions:
- 5 + 78283 = 78288
- 11 + 78277 = 78288
- 29 + 78259 = 78288
- 47 + 78241 = 78288
- 59 + 78229 = 78288
- 97 + 78191 = 78288
- 109 + 78179 = 78288
- 131 + 78157 = 78288
Showing the first eight; more decompositions exist.
