Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524000, here are decompositions:
- 47 + 31523953 = 31524000
- 59 + 31523941 = 31524000
- 61 + 31523939 = 31524000
- 83 + 31523917 = 31524000
- 149 + 31523851 = 31524000
- 197 + 31523803 = 31524000
- 199 + 31523801 = 31524000
- 239 + 31523761 = 31524000
Showing the first eight; more decompositions exist.
