Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584700, here are decompositions:

  • 3 + 2147584697 = 2147584700
  • 7 + 2147584693 = 2147584700
  • 31 + 2147584669 = 2147584700
  • 43 + 2147584657 = 2147584700
  • 97 + 2147584603 = 2147584700
  • 103 + 2147584597 = 2147584700
  • 181 + 2147584519 = 2147584700
  • 199 + 2147584501 = 2147584700

Showing the first eight; more decompositions exist.
