Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524012, here are decompositions:
- 59 + 31523953 = 31524012
- 71 + 31523941 = 31524012
- 73 + 31523939 = 31524012
- 131 + 31523881 = 31524012
- 173 + 31523839 = 31524012
- 211 + 31523801 = 31524012
- 251 + 31523761 = 31524012
- 263 + 31523749 = 31524012
Showing the first eight; more decompositions exist.
