Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546742, here are decompositions:

  • 79 + 31546663 = 31546742
  • 109 + 31546633 = 31546742
  • 151 + 31546591 = 31546742
  • 349 + 31546393 = 31546742
  • 373 + 31546369 = 31546742
  • 439 + 31546303 = 31546742
  • 463 + 31546279 = 31546742
  • 613 + 31546129 = 31546742

Showing the first eight; more decompositions exist.
