Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620184, here are decompositions:
- 17 + 31620167 = 31620184
- 53 + 31620131 = 31620184
- 191 + 31619993 = 31620184
- 383 + 31619801 = 31620184
- 443 + 31619741 = 31620184
- 461 + 31619723 = 31620184
- 467 + 31619717 = 31620184
- 641 + 31619543 = 31620184
Showing the first eight; more decompositions exist.
