Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474358, here are decompositions:
- 7 + 31474351 = 31474358
- 67 + 31474291 = 31474358
- 109 + 31474249 = 31474358
- 229 + 31474129 = 31474358
- 367 + 31473991 = 31474358
- 457 + 31473901 = 31474358
- 547 + 31473811 = 31474358
- 577 + 31473781 = 31474358
Showing the first eight; more decompositions exist.
