Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481864, here are decompositions:
- 13 + 31481851 = 31481864
- 97 + 31481767 = 31481864
- 151 + 31481713 = 31481864
- 163 + 31481701 = 31481864
- 181 + 31481683 = 31481864
- 241 + 31481623 = 31481864
- 367 + 31481497 = 31481864
- 433 + 31481431 = 31481864
Showing the first eight; more decompositions exist.
