Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527846, here are decompositions:
- 17 + 31527829 = 31527846
- 19 + 31527827 = 31527846
- 29 + 31527817 = 31527846
- 59 + 31527787 = 31527846
- 137 + 31527709 = 31527846
- 149 + 31527697 = 31527846
- 157 + 31527689 = 31527846
- 263 + 31527583 = 31527846
Showing the first eight; more decompositions exist.
