Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67780, here are decompositions:
- 3 + 67777 = 67780
- 17 + 67763 = 67780
- 23 + 67757 = 67780
- 29 + 67751 = 67780
- 47 + 67733 = 67780
- 71 + 67709 = 67780
- 101 + 67679 = 67780
- 149 + 67631 = 67780
Showing the first eight; more decompositions exist.
