Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473506, here are decompositions:
- 19 + 31473487 = 31473506
- 109 + 31473397 = 31473506
- 193 + 31473313 = 31473506
- 223 + 31473283 = 31473506
- 397 + 31473109 = 31473506
- 439 + 31473067 = 31473506
- 523 + 31472983 = 31473506
- 577 + 31472929 = 31473506
Showing the first eight; more decompositions exist.
