Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509370, here are decompositions:
- 41 + 31509329 = 31509370
- 47 + 31509323 = 31509370
- 149 + 31509221 = 31509370
- 197 + 31509173 = 31509370
- 293 + 31509077 = 31509370
- 317 + 31509053 = 31509370
- 353 + 31509017 = 31509370
- 449 + 31508921 = 31509370
Showing the first eight; more decompositions exist.
