Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972988, here are decompositions:

  • 37 + 4294972951 = 4294972988
  • 127 + 4294972861 = 4294972988
  • 181 + 4294972807 = 4294972988
  • 199 + 4294972789 = 4294972988
  • 331 + 4294972657 = 4294972988
  • 379 + 4294972609 = 4294972988
  • 409 + 4294972579 = 4294972988
  • 421 + 4294972567 = 4294972988

Showing the first eight; more decompositions exist.
