Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467530, here are decompositions:
- 97 + 31467433 = 31467530
- 163 + 31467367 = 31467530
- 229 + 31467301 = 31467530
- 271 + 31467259 = 31467530
- 331 + 31467199 = 31467530
- 349 + 31467181 = 31467530
- 373 + 31467157 = 31467530
- 397 + 31467133 = 31467530
Showing the first eight; more decompositions exist.
