Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473770, here are decompositions:
- 37 + 31473733 = 31473770
- 67 + 31473703 = 31473770
- 241 + 31473529 = 31473770
- 283 + 31473487 = 31473770
- 313 + 31473457 = 31473770
- 373 + 31473397 = 31473770
- 439 + 31473331 = 31473770
- 457 + 31473313 = 31473770
Showing the first eight; more decompositions exist.
