Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140778, here are decompositions:
- 5 + 140773 = 140778
- 17 + 140761 = 140778
- 19 + 140759 = 140778
- 37 + 140741 = 140778
- 47 + 140731 = 140778
- 61 + 140717 = 140778
- 89 + 140689 = 140778
- 97 + 140681 = 140778
Showing the first eight; more decompositions exist.
