Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69840, here are decompositions:
- 7 + 69833 = 69840
- 11 + 69829 = 69840
- 13 + 69827 = 69840
- 19 + 69821 = 69840
- 31 + 69809 = 69840
- 61 + 69779 = 69840
- 73 + 69767 = 69840
- 79 + 69761 = 69840
Showing the first eight; more decompositions exist.
