Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68478, here are decompositions:
- 5 + 68473 = 68478
- 29 + 68449 = 68478
- 31 + 68447 = 68478
- 41 + 68437 = 68478
- 79 + 68399 = 68478
- 89 + 68389 = 68478
- 107 + 68371 = 68478
- 127 + 68351 = 68478
Showing the first eight; more decompositions exist.
