Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525416, here are decompositions:
- 19 + 31525397 = 31525416
- 37 + 31525379 = 31525416
- 73 + 31525343 = 31525416
- 127 + 31525289 = 31525416
- 137 + 31525279 = 31525416
- 149 + 31525267 = 31525416
- 173 + 31525243 = 31525416
- 233 + 31525183 = 31525416
Showing the first eight; more decompositions exist.
