Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527454, here are decompositions:
- 41 + 31527413 = 31527454
- 47 + 31527407 = 31527454
- 131 + 31527323 = 31527454
- 137 + 31527317 = 31527454
- 263 + 31527191 = 31527454
- 281 + 31527173 = 31527454
- 311 + 31527143 = 31527454
- 347 + 31527107 = 31527454
Showing the first eight; more decompositions exist.
