Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678040, here are decompositions:

  • 11 + 8678029 = 8678040
  • 13 + 8678027 = 8678040
  • 29 + 8678011 = 8678040
  • 47 + 8677993 = 8678040
  • 61 + 8677979 = 8678040
  • 73 + 8677967 = 8678040
  • 79 + 8677961 = 8678040
  • 89 + 8677951 = 8678040

Showing the first eight; more decompositions exist.
