Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723080, here are decompositions:

  • 17 + 8723063 = 8723080
  • 89 + 8722991 = 8723080
  • 131 + 8722949 = 8723080
  • 167 + 8722913 = 8723080
  • 239 + 8722841 = 8723080
  • 251 + 8722829 = 8723080
  • 281 + 8722799 = 8723080
  • 419 + 8722661 = 8723080

Showing the first eight; more decompositions exist.
