Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47440, here are decompositions:
- 23 + 47417 = 47440
- 53 + 47387 = 47440
- 59 + 47381 = 47440
- 89 + 47351 = 47440
- 101 + 47339 = 47440
- 131 + 47309 = 47440
- 137 + 47303 = 47440
- 233 + 47207 = 47440
Showing the first eight; more decompositions exist.
