Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971900, here are decompositions:

  • 17 + 4294971883 = 4294971900
  • 41 + 4294971859 = 4294971900
  • 59 + 4294971841 = 4294971900
  • 71 + 4294971829 = 4294971900
  • 227 + 4294971673 = 4294971900
  • 257 + 4294971643 = 4294971900
  • 293 + 4294971607 = 4294971900
  • 337 + 4294971563 = 4294971900

Showing the first eight; more decompositions exist.
