Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535024, here are decompositions:
- 13 + 31535011 = 31535024
- 43 + 31534981 = 31535024
- 151 + 31534873 = 31535024
- 193 + 31534831 = 31535024
- 223 + 31534801 = 31535024
- 271 + 31534753 = 31535024
- 373 + 31534651 = 31535024
- 463 + 31534561 = 31535024
Showing the first eight; more decompositions exist.
