Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589928, here are decompositions:
- 5 + 31589923 = 31589928
- 37 + 31589891 = 31589928
- 59 + 31589869 = 31589928
- 61 + 31589867 = 31589928
- 67 + 31589861 = 31589928
- 101 + 31589827 = 31589928
- 109 + 31589819 = 31589928
- 151 + 31589777 = 31589928
Showing the first eight; more decompositions exist.
