Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475806, here are decompositions:
- 29 + 31475777 = 31475806
- 137 + 31475669 = 31475806
- 227 + 31475579 = 31475806
- 317 + 31475489 = 31475806
- 347 + 31475459 = 31475806
- 353 + 31475453 = 31475806
- 419 + 31475387 = 31475806
- 563 + 31475243 = 31475806
Showing the first eight; more decompositions exist.
