Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589856, here are decompositions:
- 13 + 31589843 = 31589856
- 29 + 31589827 = 31589856
- 37 + 31589819 = 31589856
- 79 + 31589777 = 31589856
- 83 + 31589773 = 31589856
- 97 + 31589759 = 31589856
- 149 + 31589707 = 31589856
- 163 + 31589693 = 31589856
Showing the first eight; more decompositions exist.
