Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533718, here are decompositions:
- 11 + 31533707 = 31533718
- 59 + 31533659 = 31533718
- 107 + 31533611 = 31533718
- 131 + 31533587 = 31533718
- 137 + 31533581 = 31533718
- 257 + 31533461 = 31533718
- 269 + 31533449 = 31533718
- 347 + 31533371 = 31533718
Showing the first eight; more decompositions exist.
