Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473200, here are decompositions:
- 13 + 31473187 = 31473200
- 37 + 31473163 = 31473200
- 139 + 31473061 = 31473200
- 163 + 31473037 = 31473200
- 271 + 31472929 = 31473200
- 313 + 31472887 = 31473200
- 349 + 31472851 = 31473200
- 373 + 31472827 = 31473200
Showing the first eight; more decompositions exist.
