Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593240, here are decompositions:
- 43 + 31593197 = 31593240
- 47 + 31593193 = 31593240
- 67 + 31593173 = 31593240
- 131 + 31593109 = 31593240
- 193 + 31593047 = 31593240
- 229 + 31593011 = 31593240
- 257 + 31592983 = 31593240
- 269 + 31592971 = 31593240
Showing the first eight; more decompositions exist.
