Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742426, here are decompositions:

  • 5 + 8742421 = 8742426
  • 47 + 8742379 = 8742426
  • 59 + 8742367 = 8742426
  • 67 + 8742359 = 8742426
  • 73 + 8742353 = 8742426
  • 79 + 8742347 = 8742426
  • 109 + 8742317 = 8742426
  • 113 + 8742313 = 8742426

Showing the first eight; more decompositions exist.
