Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80778, here are decompositions:
- 17 + 80761 = 80778
- 29 + 80749 = 80778
- 31 + 80747 = 80778
- 41 + 80737 = 80778
- 97 + 80681 = 80778
- 101 + 80677 = 80778
- 107 + 80671 = 80778
- 109 + 80669 = 80778
Showing the first eight; more decompositions exist.
