Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971866, here are decompositions:

  • 7 + 4294971859 = 4294971866
  • 37 + 4294971829 = 4294971866
  • 193 + 4294971673 = 4294971866
  • 223 + 4294971643 = 4294971866
  • 397 + 4294971469 = 4294971866
  • 487 + 4294971379 = 4294971866
  • 499 + 4294971367 = 4294971866
  • 739 + 4294971127 = 4294971866

Showing the first eight; more decompositions exist.
