Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77888, here are decompositions:
- 127 + 77761 = 77888
- 157 + 77731 = 77888
- 199 + 77689 = 77888
- 229 + 77659 = 77888
- 241 + 77647 = 77888
- 271 + 77617 = 77888
- 277 + 77611 = 77888
- 331 + 77557 = 77888
Showing the first eight; more decompositions exist.
