Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971784, here are decompositions:

  • 3 + 4294971781 = 4294971784
  • 227 + 4294971557 = 4294971784
  • 281 + 4294971503 = 4294971784
  • 293 + 4294971491 = 4294971784
  • 353 + 4294971431 = 4294971784
  • 461 + 4294971323 = 4294971784
  • 557 + 4294971227 = 4294971784
  • 563 + 4294971221 = 4294971784

Showing the first eight; more decompositions exist.
