Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78066, here are decompositions:
- 7 + 78059 = 78066
- 17 + 78049 = 78066
- 59 + 78007 = 78066
- 67 + 77999 = 78066
- 83 + 77983 = 78066
- 89 + 77977 = 78066
- 97 + 77969 = 78066
- 137 + 77929 = 78066
Showing the first eight; more decompositions exist.
