Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987040, here are decompositions:

  • 73 + 4294986967 = 4294987040
  • 151 + 4294986889 = 4294987040
  • 277 + 4294986763 = 4294987040
  • 283 + 4294986757 = 4294987040
  • 397 + 4294986643 = 4294987040
  • 601 + 4294986439 = 4294987040
  • 607 + 4294986433 = 4294987040
  • 709 + 4294986331 = 4294987040

Showing the first eight; more decompositions exist.
