Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991840, here are decompositions:

  • 3 + 4294991837 = 4294991840
  • 19 + 4294991821 = 4294991840
  • 103 + 4294991737 = 4294991840
  • 127 + 4294991713 = 4294991840
  • 163 + 4294991677 = 4294991840
  • 283 + 4294991557 = 4294991840
  • 331 + 4294991509 = 4294991840
  • 379 + 4294991461 = 4294991840

Showing the first eight; more decompositions exist.
