Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738990, here are decompositions:

  • 61 + 8738929 = 8738990
  • 109 + 8738881 = 8738990
  • 151 + 8738839 = 8738990
  • 181 + 8738809 = 8738990
  • 223 + 8738767 = 8738990
  • 277 + 8738713 = 8738990
  • 283 + 8738707 = 8738990
  • 331 + 8738659 = 8738990

Showing the first eight; more decompositions exist.
