Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723898, here are decompositions:

  • 5 + 8723893 = 8723898
  • 11 + 8723887 = 8723898
  • 19 + 8723879 = 8723898
  • 47 + 8723851 = 8723898
  • 109 + 8723789 = 8723898
  • 167 + 8723731 = 8723898
  • 191 + 8723707 = 8723898
  • 347 + 8723551 = 8723898

Showing the first eight; more decompositions exist.
