Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473250, here are decompositions:
- 41 + 31473209 = 31473250
- 47 + 31473203 = 31473250
- 59 + 31473191 = 31473250
- 89 + 31473161 = 31473250
- 167 + 31473083 = 31473250
- 173 + 31473077 = 31473250
- 359 + 31472891 = 31473250
- 383 + 31472867 = 31473250
Showing the first eight; more decompositions exist.
