Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294986638, here are decompositions:

  • 127 + 4294986511 = 4294986638
  • 199 + 4294986439 = 4294986638
  • 307 + 4294986331 = 4294986638
  • 499 + 4294986139 = 4294986638
  • 619 + 4294986019 = 4294986638
  • 727 + 4294985911 = 4294986638
  • 829 + 4294985809 = 4294986638
  • 991 + 4294985647 = 4294986638

Showing the first eight; more decompositions exist.
