Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527480, here are decompositions:
- 67 + 31527413 = 31527480
- 73 + 31527407 = 31527480
- 137 + 31527343 = 31527480
- 157 + 31527323 = 31527480
- 163 + 31527317 = 31527480
- 227 + 31527253 = 31527480
- 233 + 31527247 = 31527480
- 269 + 31527211 = 31527480
Showing the first eight; more decompositions exist.
