Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478456, here are decompositions:
- 67 + 31478389 = 31478456
- 277 + 31478179 = 31478456
- 283 + 31478173 = 31478456
- 367 + 31478089 = 31478456
- 379 + 31478077 = 31478456
- 433 + 31478023 = 31478456
- 439 + 31478017 = 31478456
- 463 + 31477993 = 31478456
Showing the first eight; more decompositions exist.
