Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987100, here are decompositions:

  • 43 + 4294987057 = 4294987100
  • 109 + 4294986991 = 4294987100
  • 193 + 4294986907 = 4294987100
  • 211 + 4294986889 = 4294987100
  • 307 + 4294986793 = 4294987100
  • 337 + 4294986763 = 4294987100
  • 457 + 4294986643 = 4294987100
  • 661 + 4294986439 = 4294987100

Showing the first eight; more decompositions exist.
