Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529538, here are decompositions:

  • 17 + 31529521 = 31529538
  • 31 + 31529507 = 31529538
  • 59 + 31529479 = 31529538
  • 67 + 31529471 = 31529538
  • 107 + 31529431 = 31529538
  • 179 + 31529359 = 31529538
  • 191 + 31529347 = 31529538
  • 269 + 31529269 = 31529538

Showing the first eight; more decompositions exist.
