Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559770, here are decompositions:
- 71 + 31559699 = 31559770
- 83 + 31559687 = 31559770
- 89 + 31559681 = 31559770
- 131 + 31559639 = 31559770
- 197 + 31559573 = 31559770
- 233 + 31559537 = 31559770
- 269 + 31559501 = 31559770
- 353 + 31559417 = 31559770
Showing the first eight; more decompositions exist.
