Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524258, here are decompositions:
- 61 + 31524197 = 31524258
- 97 + 31524161 = 31524258
- 151 + 31524107 = 31524258
- 167 + 31524091 = 31524258
- 211 + 31524047 = 31524258
- 317 + 31523941 = 31524258
- 419 + 31523839 = 31524258
- 457 + 31523801 = 31524258
Showing the first eight; more decompositions exist.
