Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523856, here are decompositions:
- 5 + 31523851 = 31523856
- 17 + 31523839 = 31523856
- 53 + 31523803 = 31523856
- 103 + 31523753 = 31523856
- 107 + 31523749 = 31523856
- 149 + 31523707 = 31523856
- 197 + 31523659 = 31523856
- 223 + 31523633 = 31523856
Showing the first eight; more decompositions exist.
