Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523976, here are decompositions:
- 23 + 31523953 = 31523976
- 37 + 31523939 = 31523976
- 59 + 31523917 = 31523976
- 137 + 31523839 = 31523976
- 173 + 31523803 = 31523976
- 223 + 31523753 = 31523976
- 227 + 31523749 = 31523976
- 269 + 31523707 = 31523976
Showing the first eight; more decompositions exist.
