Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69440, here are decompositions:
- 13 + 69427 = 69440
- 37 + 69403 = 69440
- 61 + 69379 = 69440
- 103 + 69337 = 69440
- 127 + 69313 = 69440
- 181 + 69259 = 69440
- 193 + 69247 = 69440
- 277 + 69163 = 69440
Showing the first eight; more decompositions exist.
