Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724980, here are decompositions:

  • 13 + 8724967 = 8724980
  • 31 + 8724949 = 8724980
  • 37 + 8724943 = 8724980
  • 97 + 8724883 = 8724980
  • 109 + 8724871 = 8724980
  • 181 + 8724799 = 8724980
  • 193 + 8724787 = 8724980
  • 241 + 8724739 = 8724980

Showing the first eight; more decompositions exist.
