Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526816, here are decompositions:
- 7 + 31526809 = 31526816
- 43 + 31526773 = 31526816
- 67 + 31526749 = 31526816
- 103 + 31526713 = 31526816
- 127 + 31526689 = 31526816
- 199 + 31526617 = 31526816
- 283 + 31526533 = 31526816
- 313 + 31526503 = 31526816
Showing the first eight; more decompositions exist.
