Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627440, here are decompositions:
- 29 + 31627411 = 31627440
- 67 + 31627373 = 31627440
- 83 + 31627357 = 31627440
- 107 + 31627333 = 31627440
- 137 + 31627303 = 31627440
- 151 + 31627289 = 31627440
- 179 + 31627261 = 31627440
- 191 + 31627249 = 31627440
Showing the first eight; more decompositions exist.
