Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524156, here are decompositions:
- 23 + 31524133 = 31524156
- 107 + 31524049 = 31524156
- 109 + 31524047 = 31524156
- 113 + 31524043 = 31524156
- 239 + 31523917 = 31524156
- 317 + 31523839 = 31524156
- 353 + 31523803 = 31524156
- 449 + 31523707 = 31524156
Showing the first eight; more decompositions exist.
