Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524800, here are decompositions:
- 3 + 31524797 = 31524800
- 7 + 31524793 = 31524800
- 37 + 31524763 = 31524800
- 79 + 31524721 = 31524800
- 127 + 31524673 = 31524800
- 157 + 31524643 = 31524800
- 193 + 31524607 = 31524800
- 277 + 31524523 = 31524800
Showing the first eight; more decompositions exist.
