Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524248, here are decompositions:
- 157 + 31524091 = 31524248
- 199 + 31524049 = 31524248
- 307 + 31523941 = 31524248
- 331 + 31523917 = 31524248
- 367 + 31523881 = 31524248
- 397 + 31523851 = 31524248
- 409 + 31523839 = 31524248
- 487 + 31523761 = 31524248
Showing the first eight; more decompositions exist.
