Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562440, here are decompositions:
- 11 + 31562429 = 31562440
- 17 + 31562423 = 31562440
- 83 + 31562357 = 31562440
- 149 + 31562291 = 31562440
- 167 + 31562273 = 31562440
- 179 + 31562261 = 31562440
- 197 + 31562243 = 31562440
- 227 + 31562213 = 31562440
Showing the first eight; more decompositions exist.
