Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749538, here are decompositions:

  • 181 + 8749357 = 8749538
  • 229 + 8749309 = 8749538
  • 331 + 8749207 = 8749538
  • 397 + 8749141 = 8749538
  • 547 + 8748991 = 8749538
  • 661 + 8748877 = 8749538
  • 691 + 8748847 = 8749538
  • 727 + 8748811 = 8749538

Showing the first eight; more decompositions exist.
