Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620178, here are decompositions:
- 11 + 31620167 = 31620178
- 47 + 31620131 = 31620178
- 71 + 31620107 = 31620178
- 197 + 31619981 = 31620178
- 389 + 31619789 = 31620178
- 419 + 31619759 = 31620178
- 461 + 31619717 = 31620178
- 509 + 31619669 = 31620178
Showing the first eight; more decompositions exist.
