Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610780, here are decompositions:

  • 41 + 8610739 = 8610780
  • 43 + 8610737 = 8610780
  • 131 + 8610649 = 8610780
  • 137 + 8610643 = 8610780
  • 163 + 8610617 = 8610780
  • 173 + 8610607 = 8610780
  • 179 + 8610601 = 8610780
  • 181 + 8610599 = 8610780

Showing the first eight; more decompositions exist.
