Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67868, here are decompositions:
- 61 + 67807 = 67868
- 67 + 67801 = 67868
- 79 + 67789 = 67868
- 109 + 67759 = 67868
- 127 + 67741 = 67868
- 331 + 67537 = 67868
- 337 + 67531 = 67868
- 379 + 67489 = 67868
Showing the first eight; more decompositions exist.
