Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618232, here are decompositions:
- 43 + 31618189 = 31618232
- 229 + 31618003 = 31618232
- 271 + 31617961 = 31618232
- 379 + 31617853 = 31618232
- 421 + 31617811 = 31618232
- 601 + 31617631 = 31618232
- 673 + 31617559 = 31618232
- 739 + 31617493 = 31618232
Showing the first eight; more decompositions exist.
