Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723858, here are decompositions:

  • 7 + 8723851 = 8723858
  • 37 + 8723821 = 8723858
  • 127 + 8723731 = 8723858
  • 151 + 8723707 = 8723858
  • 181 + 8723677 = 8723858
  • 307 + 8723551 = 8723858
  • 337 + 8723521 = 8723858
  • 379 + 8723479 = 8723858

Showing the first eight; more decompositions exist.
