Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460786, here are decompositions:

  • 3 + 31460783 = 31460786
  • 43 + 31460743 = 31460786
  • 109 + 31460677 = 31460786
  • 139 + 31460647 = 31460786
  • 277 + 31460509 = 31460786
  • 373 + 31460413 = 31460786
  • 439 + 31460347 = 31460786
  • 457 + 31460329 = 31460786

Showing the first eight; more decompositions exist.
