Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971478, here are decompositions:

  • 47 + 4294971431 = 4294971478
  • 89 + 4294971389 = 4294971478
  • 101 + 4294971377 = 4294971478
  • 251 + 4294971227 = 4294971478
  • 257 + 4294971221 = 4294971478
  • 269 + 4294971209 = 4294971478
  • 401 + 4294971077 = 4294971478
  • 419 + 4294971059 = 4294971478

Showing the first eight; more decompositions exist.
