Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294965978, here are decompositions:

  • 7 + 4294965971 = 4294965978
  • 11 + 4294965967 = 4294965978
  • 29 + 4294965949 = 4294965978
  • 41 + 4294965937 = 4294965978
  • 67 + 4294965911 = 4294965978
  • 131 + 4294965847 = 4294965978
  • 137 + 4294965841 = 4294965978
  • 139 + 4294965839 = 4294965978

Showing the first eight; more decompositions exist.
