Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987886, here are decompositions:

  • 37 + 4294987849 = 4294987886
  • 307 + 4294987579 = 4294987886
  • 499 + 4294987387 = 4294987886
  • 829 + 4294987057 = 4294987886
  • 919 + 4294986967 = 4294987886
  • 997 + 4294986889 = 4294987886
  • 1093 + 4294986793 = 4294987886
  • 1123 + 4294986763 = 4294987886

Showing the first eight; more decompositions exist.
