Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971578, here are decompositions:

  • 109 + 4294971469 = 4294971578
  • 199 + 4294971379 = 4294971578
  • 211 + 4294971367 = 4294971578
  • 229 + 4294971349 = 4294971578
  • 277 + 4294971301 = 4294971578
  • 379 + 4294971199 = 4294971578
  • 409 + 4294971169 = 4294971578
  • 739 + 4294970839 = 4294971578

Showing the first eight; more decompositions exist.
