Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527848, here are decompositions:
- 19 + 31527829 = 31527848
- 31 + 31527817 = 31527848
- 61 + 31527787 = 31527848
- 67 + 31527781 = 31527848
- 139 + 31527709 = 31527848
- 151 + 31527697 = 31527848
- 271 + 31527577 = 31527848
- 307 + 31527541 = 31527848
Showing the first eight; more decompositions exist.
