Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526876, here are decompositions:
- 13 + 31526863 = 31526876
- 67 + 31526809 = 31526876
- 103 + 31526773 = 31526876
- 127 + 31526749 = 31526876
- 163 + 31526713 = 31526876
- 229 + 31526647 = 31526876
- 313 + 31526563 = 31526876
- 349 + 31526527 = 31526876
Showing the first eight; more decompositions exist.
