Goldbach decomposition

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.
