Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630820, here are decompositions:

  • 7 + 8630813 = 8630820
  • 31 + 8630789 = 8630820
  • 41 + 8630779 = 8630820
  • 61 + 8630759 = 8630820
  • 71 + 8630749 = 8630820
  • 83 + 8630737 = 8630820
  • 137 + 8630683 = 8630820
  • 151 + 8630669 = 8630820

Showing the first eight; more decompositions exist.
