Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971808, here are decompositions:

  • 251 + 4294971557 = 4294971808
  • 311 + 4294971497 = 4294971808
  • 317 + 4294971491 = 4294971808
  • 419 + 4294971389 = 4294971808
  • 431 + 4294971377 = 4294971808
  • 587 + 4294971221 = 4294971808
  • 599 + 4294971209 = 4294971808
  • 929 + 4294970879 = 4294971808

Showing the first eight; more decompositions exist.
