Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723874, here are decompositions:

  • 23 + 8723851 = 8723874
  • 41 + 8723833 = 8723874
  • 53 + 8723821 = 8723874
  • 67 + 8723807 = 8723874
  • 167 + 8723707 = 8723874
  • 197 + 8723677 = 8723874
  • 281 + 8723593 = 8723874
  • 353 + 8723521 = 8723874

Showing the first eight; more decompositions exist.
